SLAPD.CONF(5)SLAPD.CONF(5)NAME
slapd.conf - configuration file for slapd, the stand-alone LDAP daemon
SYNOPSIS
/etc/openldap/slapd.conf
DESCRIPTION
The file /etc/openldap/slapd.conf contains configuration information
for the slapd(8) daemon. This configuration file is also used by the
slurpd(8) replication daemon and by the SLAPD tools slapadd(8), slap‐
cat(8), and slapindex(8).
The slapd.conf file consists of a series of global configuration
options that apply to slapd as a whole (including all backends), fol‐
lowed by zero or more database backend definitions that contain infor‐
mation specific to a backend instance.
The general format of slapd.conf is as follows:
# comment - these options apply to every database
<global configuration options>
# first database definition & configuration options
database <backend 1 type>
<configuration options specific to backend 1>
# subsequent database definitions & configuration options
...
As many backend-specific sections as desired may be included. Global
options can be overridden in a backend (for options that appear more
than once, the last appearance in the slapd.conf file is used). Blank
lines and comment lines beginning with a `#' character are ignored. If
a line begins with white space, it is considered a continuation of the
previous line.
Arguments on configuration lines are separated by white space. If an
argument contains white space, the argument should be enclosed in dou‐
ble quotes. If an argument contains a double quote (`"') or a back‐
slash character (`\'), the character should be preceded by a backslash
character.
The specific configuration options available are discussed below in the
Global Configuration Options, General Backend Options, and General
Database Options. Backend-specific options are discussed in the
slapd-<backend>(5) manual pages. Refer to the "OpenLDAP Administra‐
tor's Guide" for more details on the slapd configuration file.
GLOBAL CONFIGURATION OPTIONS
Options described in this section apply to all backends, unless specif‐
ically overridden in a backend definition. Arguments that should be
replaced by actual text are shown in brackets <>.
access to <what> [ by <who> <access> <control> ]+
Grant access (specified by <access>) to a set of entries and/or
attributes (specified by <what>) by one or more requestors
(specified by <who>). See slapd.access(5) and the "OpenLDAP's
Administrator's Guide" for details.
allow <features>
Specify a set of features (separated by white space) to allow
(default none). bind_v2 allows acceptance of LDAPv2 bind
requests. Note that slapd(8) does not truely implement LDAPv2
(RFC 1777), now Historic (RFC 3494). bind_anon_cred allows
anonymous bind when credentials are not empty (e.g. when DN is
empty). bind_anon_dn allows unauthenticated (anonymous) bind
when DN is not empty. update_anon allow unauthenticated (anony‐
mous) update operations to be processed (subject to access con‐
trols and other administrative limits).
argsfile <filename>
The ( absolute ) name of a file that will hold the slapd
server's command line options if started without the debugging
command line option.
attributeoptions [option-name]...
Define tagging attribute options or option tag/range prefixes.
Options must not end with `-', prefixes must end with `-'. The
`lang-' prefix is predefined. If you use the attributeoptions
directive, `lang-' will no longer be defined and you must spec‐
ify it explicitly if you want it defined.
An attribute description with a tagging option is a subtype of
that attribute description without the option. Except for that,
options defined this way have no special semantics. Prefixes
defined this way work like the `lang-' options: They define a
prefix for tagging options starting with the prefix. That is,
if you define the prefix `x-foo-', you can use the option `x-
foo-bar'. Furthermore, in a search or compare, a prefix or
range name (with a trailing `-') matches all options starting
with that name, as well as the option with the range name sans
the trailing `-'. That is, `x-foo-bar-' matches `x-foo-bar' and
`x-foo-bar-baz'.
RFC2251 reserves options beginning with `x-' for private experi‐
ments. Other options should be registered with IANA, see
RFC3383 section 3.4. OpenLDAP also has the `binary' option
built in, but this is a transfer option, not a tagging option.
attributetype ( <oid> [NAME <name>] [OBSOLETE] [DESC <description>]
[SUP <oid>] [EQUALITY <oid>] [ORDERING <oid>] [SUBSTR <oid>]
[SYNTAX <oidlen>] [SINGLE-VALUE] [COLLECTIVE]
[NO-USER-MODIFICATION] [USAGE <attributeUsage>] )
Specify an attribute type using the LDAPv3 syntax defined in RFC
2252. The slapd parser extends the RFC 2252 definition by
allowing string forms as well as numeric OIDs to be used for the
attribute OID and attribute syntax OID. (See the
objectidentifier description.)
concurrency <integer>
Specify a desired level of concurrency. Provided to the
underlying thread system as a hint. The default is not to
provide any hint.
conn_max_pending <integer>
Specify the maximum number of pending requests for an anonymous
session. If requests are submitted faster than the server can
process them, they will be queued up to this limit. If the limit
is exceeded, the session is closed. The default is 100.
conn_max_pending_auth <integer>
Specify the maximum number of pending requests for an
authenticated session. The default is 1000.
defaultsearchbase <dn>
Specify a default search base to use when client submits a non-
base search request with an empty base DN.
disallow <features>
Specify a set of features (separated by white space) to disallow
(default none). bind_anon disables acceptance of anonymous bind
requests. bind_simple disables simple (bind) authentication.
bind_krbv4 disables Kerberos V4 (bind) authentication.
tls_2_anon disables Start TLS from forcing session to anonymous
status (see also tls_authc). tls_authc disables StartTLS if
authenticated (see also tls_2_anon).
gentlehup { on | off }
A SIGHUP signal will only cause a 'gentle' shutdown-attempt:
Slapd will stop listening for new connections, but will not
close the connections to the current clients. Future write
operations return unwilling-to-perform, though. Slapd
terminates when all clients have closed their connections (if
they ever do), or - as before - if it receives a SIGTERM signal.
This can be useful if you wish to terminate the server and start
a new slapd server with another database, without disrupting the
currently active clients. The default is off. You may wish to
use idletimeout along with this option.
idletimeout <integer>
Specify the number of seconds to wait before forcibly closing an
idle client connection. A idletimeout of 0 disables this
feature. The default is 0.
include <filename>
Read additional configuration information from the given file
before continuing with the next line of the current file.
limits <who> <limit> [<limit> [...]]
Specify time and size limits based on who initiated an
operation. The argument who can be any of
anonymous | users | [dn[.<style>]=]<pattern>
with
<style> ::= exact | base | one | subtree | children |
regex | anonymous
Anonymous is hit when a search is performed without prior
binding; users is hit when a search is performed by a
successfully bound user; otherwise a regex dn pattern is assumed
unless otherwise specified by qualifying the (optional) key
string dn with exact or base (which are synonims), to require an
exact match; with one, to require exactly one level of depth
match; with subtree, to allow any level of depth match,
including the exact match; with children, to allow any level of
depth match, not including the exact match; regex explicitly
requires the (default) match based on regular expression
pattern, as detailed in regex(7). Finally, anonymous matches
unbound operations; the pattern field is ignored. The same
behavior is obtained by using the anonymous form of the who
clause.
The currently supported limits are size and time.
The syntax for time limits is time[.{soft|hard}]=<integer>,
where integer is the number of seconds slapd will spend
answering a search request. If no time limit is explicitly
requested by the client, the soft limit is used; if the
requested time limit exceedes the hard limit, an "Administrative
limit exceeded" is returned. If the hard limit is set to 0 or
to the keyword "soft", the soft limit is used in either case; if
it is set to -1 or to the keyword "none", no hard limit is
enforced. Explicit requests for time limits smaller or equal to
the hard limit are honored. If no flag is set, the value is
assigned to the soft limit, and the hard limit is set to zero,
to preserve the original behavior.
The syntax for size limits is
size[.{soft|hard|unchecked}]=<integer>, where integer is the
maximum number of entries slapd will return answering a search
request. If no size limit is explicitly requested by the
client, the soft limit is used; if the requested size limit
exceedes the hard limit, an "Administrative limit exceeded" is
returned. If the hard limit is set to 0 or to the keyword
"soft", the soft limit is used in either case; if it is set to
-1 or to the keyword "none", no hard limit is enforced.
Explicit requests for size limits smaller or equal to the hard
limit are honored. The unchecked flag sets a limit on the
number of candidates a search request is allowed to examine. If
the selected candidates exceed the unchecked limit, the search
will abort with "Unwilling to perform". If it is set to -1 or
to the keyword "none", no limit is applied (the default). If no
flag is set, the value is assigned to the soft limit, and the
hard limit is set to zero, to preserve the original behavior.
In case of no match, the global limits are used. The default
values are the same of sizelimit and timelimit; no limit is set
on unchecked.
loglevel <integer>
Specify the level at which debugging statements and operation
statistics should be syslogged (currently logged to the
syslogd(8) LOG_LOCAL4 facility). Log levels are additive, and
available levels are:
1 trace function calls
2 debug packet handling
4 heavy trace debugging
8 connection management
16 print out packets sent and received
32 search filter processing
64 configuration file processing
128 access control list processing
256 stats log connections/operations/results
512 stats log entries sent
1024 print communication with shell backends
2048 entry parsing
moduleload <filename>
Specify the name of a dynamically loadable module to load. The
filename may be an absolute path name or a simple filename. Non-
absolute names are searched for in the directories specified by
the modulepath option. This option and the modulepath option are
only usable if slapd was compiled with --enable-modules.
modulepath <pathspec>
Specify a list of directories to search for loadable modules.
Typically the path is colon-separated but this depends on the
operating system.
objectclass ( <oid> [NAME <name>] [DESC <description] [OBSOLETE] [SUP
<oids>] [{ ABSTRACT | STRUCTURAL | AUXILIARY }] [MUST <oids>]
[MAY <oids>] )
Specify an objectclass using the LDAPv3 syntax defined in RFC
2252. The slapd parser extends the RFC 2252 definition by
allowing string forms as well as numeric OIDs to be used for the
object class OID. (See the objectidentifier description.)
Object classes are "STRUCTURAL" by default.
objectidentifier <name> { <oid> | <name>[:<suffix>] }
Define a string name that equates to the given OID. The string
can be used in place of the numeric OID in objectclass and
attribute definitions. The name can also be used with a suffix
of the form ":xx" in which case the value "oid.xx" will be used.
password-hash <hash>
This option sets the hash to be used in generation of user
passwords, stored in userPassword, during processing of LDAP
Password Modify Extended Operations (RFC 3052). The <hash> must
be one of {SSHA}, {SHA}, {SMD5}, {MD5}, {CRYPT}, and
{CLEARTEXT}. The default is {SSHA}.
{SHA} and {SSHA} use the SHA-1 algorithm (FIPS 160-1), the
latter with a seed.
{MD5} and {SMD5} use the MD5 algorithm (RFC 1321), the latter
with a seed.
{CRYPT} uses the crypt(3).
{CLEARTEXT} indicates that the new password should be added to
userPassword as clear text.
Note that this option does not alter the normal user
applications handling of userPassword during LDAP Add, Modify,
or other LDAP operations.
password-crypt-salt-format <format>
Specify the format of the salt passed to crypt(3) when
generating {CRYPT} passwords (see password-hash) during
processing of LDAP Password Modify Extended Operations (RFC
3062).
This string needs to be in sprintf(3) format and may include one
(and only one) %s conversion. This conversion will be
substituted with a string random characters from [A-Za-z0-9./].
For example, "%.2s" provides a two character salt and "$1$%.8s"
tells some versions of crypt(3) to use an MD5 algorithm and
provides 8 random characters of salt. The default is "%s",
which provides 31 characters of salt.
pidfile <filename>
The ( absolute ) name of a file that will hold the slapd
server's process ID ( see getpid(2) ) if started without the
debugging command line option.
referral <url>
Specify the referral to pass back when slapd(8) cannot find a
local database to handle a request. If specified multiple
times, each url is provided.
require <conditions>
Specify a set of conditions (separated by white space) to
require (default none). The directive may be specified globally
and/or per-database. bind requires bind operation prior to
directory operations. LDAPv3 requires session to be using LDAP
version 3. authc requires authentication prior to directory
operations. SASL requires SASL authentication prior to
directory operations. strong requires strong authentication
prior to directory operations. The strong keyword allows
protected "simple" authentication as well as SASL
authentication. none may be used to require no conditions
(useful for clearly globally set conditions within a particular
database).
reverse-lookup on | off
Enable/disable client name unverified reverse lookup (default is
off if compiled with --enable-rlookups).
rootDSE <file>
Specify the name of an LDIF(5) file containing user defined
attributes for the root DSE. These attributes are returned in
addition to the attributes normally produced by slapd.
sasl-authz-policy <policy>
Used to specify which rules to use for SASL Proxy Authorization.
Proxy authorization allows a client to authenticate to the
server using one user's credentials, but specify a different
identity to use for authorization and access control purposes.
It essentially allows user A to login as user B, using user A's
password. The none flag disables proxy authorization. This is
the default setting. The from flag will use rules in the
saslAuthzFrom attribute of the authorization DN. The to flag
will use rules in the saslAuthzTo attribute of the
authentication DN. The both flag will allow both of the above.
The rules are simply regular expressions specifying which DNs
are allowed to perform proxy authorization. The saslAuthzFrom
attribute in an entry specifies which other users are allowed to
proxy login to this entry. The saslAuthzTo attribute in an entry
specifies which other users this user can authorize as. Use of
saslAuthzTo rules can be easily abused if users are allowed to
write arbitrary values to this attribute. In general the
saslAuthzTo attribute must be protected with ACLs such that only
privileged users can modify it.
sasl-host <fqdn>
Used to specify the fully qualified domain name used for SASL
processing.
sasl-realm <realm>
Specify SASL realm. Default is empty.
sasl-regexp <match> <replace>
Used by the SASL authorization mechanism to convert a SASL
authenticated username to an LDAP DN. When an authorization
request is received, the SASL USERNAME, REALM, and MECHANISM are
taken, when available, and combined into a SASL name of the form
uid=<username>[,cn=<realm>],cn=<mechanism>,cn=auth
This SASL name is then compared against the match regular
expression, and if the match is successful, the SASL name is
replaced with the replace string. If there are wildcard strings
in the match regular expression that are enclosed in
parenthesis, e.g.
uid=(.*),cn=.*
then the portion of the SASL name that matched the wildcard will
be stored in the numbered placeholder variable $1. If there are
other wildcard strings in parenthesis, the matching strings will
be in $2, $3, etc. up to $9. The placeholders can then be used
in the replace string, e.g.
cn=$1,ou=Accounts,dc=$2,dc=$4.
The replaced SASL name can be either a DN or an LDAP URI. If the
latter, the slapd server will use the URI to search its own
database, and if the search returns exactly one entry, the SASL
name is replaced by the DN of that entry. Multiple sasl-regexp
options can be given in the configuration file to allow for
multiple matching and replacement patterns. The matching
patterns are checked in the order they appear in the file,
stopping at the first successful match.
sasl-secprops <properties>
Used to specify Cyrus SASL security properties. The none flag
(without any other properities) causes the flag properites
default, "noanonymous,noplain", to be cleared. The noplain flag
disables mechanisms susceptible to simple passive attacks. The
noactive flag disables mechanisms susceptible to active attacks.
The nodict flag disables mechanisms susceptible to passive
dictionary attacks. The noanonymous flag disables mechanisms
which support anonymous login. The forwardsec flag require
forward secrecy between sessions. The passcred require
mechanisms which pass client credentials (and allow mechanisms
which can pass credentials to do so). The minssf=<factor>
property specifies the minimum acceptable security strength
factor as an integer approximate to effective key length used
for encryption. 0 (zero) implies no protection, 1 implies
integrity protection only, 56 allows DES or other weak ciphers,
112 allows triple DES and other strong ciphers, 128 allows RC4,
Blowfish and other modern strong ciphers. The default is 0.
The maxssf=<factor> property specifies the maximum acceptable
security strength factor as an integer (see minssf description).
The default is INT_MAX. The maxbufsize=<size> property
specifies the maximum security layer receive buffer size
allowed. 0 disables security layers. The default is 65536.
schemadn <dn>
Specify the distinguished name for the subschema subentry that
controls the entries on this server. The default is
"cn=Subschema".
security <factors>
Specify a set of factors (separated by white space) to require.
An integer value is associated with each factor and is roughly
equivalent of the encryption key length to require. A value of
112 is equivalent to 3DES, 128 to Blowfish, etc.. The directive
may be specified globally and/or per-database. ssf=<n>
specifies the overall security strength factor. transport=<n>
specifies the transport security strength factor. tls=<n>
specifies the TLS security strength factor. sasl=<n> specifies
the SASL security strength factor. update_ssf=<n> specifies the
overall security strength factor to require for directory
updates. update_transport=<n> specifies the transport security
strength factor to require for directory updates.
update_tls=<n> specifies the TLS security strength factor to
require for directory updates. update_sasl=<n> specifies the
SASL security strength factor to require for directory updates.
simple_bind=<n> specifies the security strength factor required
for simple username/password authentication. Note that the
transport factor is measure of security provided by the
underlying transport, e.g. ldapi:// (and eventually IPSEC). It
is not normally used.
sizelimit {<integer>|unlimited}
sizelimit size[.{soft|hard|unchecked}]=<integer> [...]
Specify the maximum number of entries to return from a search
operation. The default size limit is 500. Use -1 or unlimited
to specify no limits. The second format allows a fine grain
setting of the size limits. Extra args can be added on the same
line. See limits for an explanation of the different flags.
sockbuf_max_incoming <integer>
Specify the maximum incoming LDAP PDU size for anonymous
sessions. The default is 262143.
sockbuf_max_incoming_auth <integer>
Specify the maximum incoming LDAP PDU size for authenticated
sessions. The default is 4194303.
srvtab <filename>
Specify the srvtab file in which the kerberos keys necessary for
authenticating clients using kerberos can be found. This option
is only meaningful if you are using Kerberos authentication.
threads <integer>
Specify the maximum size of the primary thread pool. The
default is 16.
timelimit {<integer>|unlimited}
timelimit time[.{soft|hard}]=<integer> [...]
Specify the maximum number of seconds (in real time) slapd will
spend answering a search request. The default time limit is
3600. Use -1 or unlimited to specify no limits. The second
format allows a fine grain setting of the time limits. Extra
args can be added on the same line. See limits for an
explanation of the different flags.
ucdata-path <path>
Specify the path to the directory containing the Unicode
character tables. The default path is /var/db/openldap/ucdata.
TLS OPTIONS
If slapd is built with support for Transport Layer Security, there are
more options you can specify.
TLSCipherSuite <cipher-suite-spec>
Permits configuring what ciphers will be accepted and the
preference order. <cipher-suite-spec> should be a cipher
specification for OpenSSL. Example:
TLSCipherSuite HIGH:MEDIUM:+SSLv2
To check what ciphers a given spec selects, use:
openssl ciphers -v <cipher-suite-spec>
TLSCACertificateFile <filename>
Specifies the file that contains certificates for all of the
Certificate Authorities that slapd will recognize.
TLSCACertificatePath <path>
Specifies the path of a directory that contains Certificate
Authority certificates in separate individual files. Usually
only one of this or the TLSCACertificateFile is used.
TLSCertificateFile <filename>
Specifies the file that contains the slapd server certificate.
TLSCertificateKeyFile <filename>
Specifies the file that contains the slapd server private key
that matches the certificate stored in the TLSCertificateFile
file. Currently, the private key must not be protected with a
password, so it is of critical importance that it is protected
carefully.
TLSRandFile <filename>
Specifies the file to obtain random bits from when
/dev/[u]random is not available. Generally set to the name of
the EGD/PRNGD socket. The environment variable RANDFILE can
also be used to specify the filename.
TLSVerifyClient <level>
Specifies what checks to perform on client certificates in an
incoming TLS session, if any. The <level> can be specified as
one of the following keywords:
never This is the default. slapd will not ask the client for a
certificate.
allow The client certificate is requested. If no certificate
is provided, the session proceeds normally. If a bad
certificate is provided, it will be ignored and the
session proceeds normally.
try The client certificate is requested. If no certificate
is provided, the session proceeds normally. If a bad
certificate is provided, the session is immediately
terminated.
demand | hard | true
These keywords are all equivalent, for compatibility
reasons. The client certificate is requested. If no
certificate is provided, or a bad certificate is
provided, the session is immediately terminated.
Note that a valid client certificate is required in order
to use the SASL EXTERNAL authentication mechanism with a
TLS session. As such, a non-default TLSVerifyClient
setting must be chosen to enable SASL EXTERNAL
authentication.
GENERAL BACKEND OPTIONS
Options in this section only apply to the configuration file section
for the specified backend. They are supported by every type of
backend.
backend <databasetype>
Mark the beginning of a backend definition. <databasetype>
should be one of bdb, dnssrv, ldap, ldbm, meta, monitor, null,
passwd, perl, shell, sql, or tcl, depending on which backend
will serve the database.
GENERAL DATABASE OPTIONS
Options in this section only apply to the configuration file section
for the database in which they are defined. They are supported by
every type of backend. Note that the database and at least one suffix
option are mandatory for each database.
database <databasetype>
Mark the beginning of a new database instance definition.
<databasetype> should be one of bdb, dnssrv, ldap, ldbm, meta,
monitor, null, passwd, perl, shell, sql, or tcl, depending on
which backend will serve the database.
lastmod on | off
Controls whether slapd will automatically maintain the
modifiersName, modifyTimestamp, creatorsName, and
createTimestamp attributes for entries. By default, lastmod is
on.
maxderefdepth <depth>
Specifies the maximum number of aliases to dereference when
trying to resolve an entry, used to avoid inifinite alias loops.
The default is 1.
readonly on | off
This option puts the database into "read-only" mode. Any
attempts to modify the database will return an "unwilling to
perform" error. By default, readonly is off.
replica host=<hostname>[:port] [tls=yes|critical] [suffix=<suffix>
[...]] bindmethod=simple|sasl [binddn=<simple DN>]
[credentials=<simple password>] [saslmech=<SASL mech>]
[secprops=<properties>] [realm=<realm>] [authcId=<authentication
ID>] [authzId=<authorization ID>] [attr[!]=<attr list>]
Specify a replication site for this database. Refer to the
"OpenLDAP Administrator's Guide" for detailed information on
setting up a replicated slapd directory service. Zero or more
suffix instances can be used to select the subtrees that will be
replicated (defaults to all the database). A bindmethod of
simple requires the options binddn and credentials and should
only be used when adequate security services (e.g TLS or IPSEC)
are in place. A bindmethod of sasl requires the option saslmech.
Specific security properties (as with the sasl-secprops keyword
above) for a SASL bind can be set with the secprops option. A
non-default SASL realm can be set with the realm option. If the
mechanism will use Kerberos, a kerberos instance should be given
in authcId. An attr list can be given after the attr keyword to
allow the selective replication of the listed attributes only;
if the optional ! mark is used, the list is considered
exclusive, i.e. the listed attributes are not replicated. If an
objectClass is listed, all the related attributes are (are not)
replicated.
replogfile <filename>
Specify the name of the replication log file to log changes to.
The replication log is typically written by slapd(8) and read by
slurpd(8). See slapd.replog(5) for more information. The
specified file should be located in a directory with limited
read/write/execute access as the replication logs may contain
sensitive information.
rootdn <dn>
Specify the distinguished name that is not subject to access
control or administrative limit restrictions for operations on
this database. This DN may or may not be associated with an
entry. An empty root DN (the default) specifies no root access
is to be granted. It is recommended that the rootdn only be
specified when needed (such as when initially populating a
database). If the rootdn is within a namingContext (suffix) of
the database, a simple bind password may also be provided using
the rootpw directive.
rootpw <password>
Specify a password (or hash of the password) for the rootdn.
The password can only be set if the rootdn is within the
namingContext (suffix) of the database. This option accepts all
RFC 2307 userPassword formats known to the server (see password-
hash desription) as well as cleartext. slappasswd(8) may be
used to generate a hash of a password. Cleartext and {CRYPT}
passwords are not recommended. If empty (the default),
authentication of the root DN is by other means (e.g. SASL).
Use of SASL is encouraged.
suffix <dn suffix>
Specify the DN suffix of queries that will be passed to this
backend database. Multiple suffix lines can be given and at
least one is required for each database definition. If the
suffix of one database is "inside" that of another, the database
with the inner suffix must come first in the configuration file.
subordinate
Specify that the current backend database is a subordinate of
another backend database. A subordinate database may have only
one suffix. This option may be used to glue multiple databases
into a single namingContext. If the suffix of the current
database is within the namingContext of a superior database,
searches against the superior database will be propagated to the
subordinate as well. All of the databases associated with a
single namingContext should have identical rootdns. Behavior of
other LDAP operations is unaffected by this setting. In
particular, it is not possible to use moddn to move an entry
from one subordinate to another subordinate within the
namingContext.
updatedn <dn>
This option is only applicable in a slave slapd. It specifies
the DN allowed to make changes to the replica (typically, this
is the DN slurpd(8) binds as when making changes to the
replica).
updateref <url>
Specify the referral to pass back when slapd(8) is asked to
modify a replicated local database. If specified multiple
times, each url is provided.
DATABASE-SPECIFIC OPTIONS
Each database may allow specific configuration options; they are
documented separately in the slapd-<backend>(5) manual pages.
EXAMPLES
Here is a short example of a configuration file:
