SYNOPSIS
use Net::LDAP;
use Net::LDAP::Schema;
#
# Read schema from server
#
$ldap = Net::LDAP->new ( $server );
$ldap->bind ( );
$schema = $ldap->schema ( );
#
# Load from LDIF
#
$schema = Net::LDAP::Schema->new;
$schema->parse ( "schema.ldif" ) or die $schema->error;
DESCRIPTION
"Net::LDAP::Schema" provides a means to load an LDAP schema and query
it for information regarding supported objectclasses, attributes and
syntaxes.
METHODS
Where a method is stated as taking the 'name or oid' of a schema item
(which may be an object class, attribute or syntax) then a case-insen‐
sitive name or raw oid (object identifier, in dotted numeric string
form, e.g. 2.5.4.0) may be supplied.
Each returned item of schema (eg an attribute definition) is returned
in a HASH. The keys in the returned HASH are lowercased versions of the
keys read from the server. Here's a partial list (not all HASHes define
all keys) although note that RFC 2252 permits other keys as well:
name
desc
obsolete
sup
equality
ordering
substr
syntax
single-value
collective
no-user-modification
usage
abstract
structural
auxiliary
must
may
applies
aux
not
oc
form
all_attributes ( )
all_ditcontentrules ( )
all_ditstructurerules ( )
all_matchingrules ( )
all_matchingruleuses ( )
all_nameforms ( )
all_objectclasses ( )
all_syntaxes ( )
Returns a list of all the requested types in the schema.
attribute ( NAME )
ditcontentrule ( NAME )
ditstructurerule ( NAME )
matchingrule ( NAME )
matchingruleuse ( NAME )
nameform ( NAME )
objectclass ( NAME )
syntax ( NAME )
Returns a reference to a hash, or "undef" if the schema item does
not exist. "NAME" can be a name or an OID.
$attr_href = $schema->attribute( "attrname" );
dump ( )
Dump the raw schema information to standard out.
dump ( FILENAME )
Dump the raw schema information to a file.
$result = $schema->dump ( "./schema.dump" );
If no schema data is returned from directory server, the method
will return undefined. Otherwise a value of 1 is always returned.
error ( )
Returns the last error encountered when parsing the schema.
may ( OBJECTCLASS )
Given an argument which is the name or oid of a known object class,
returns a list of HASHes describing the attributes which are
optional in the class.
@may = $schema->may ( $oc );
# First optional attr has the name '$may[0]->{name}'
must ( OBJECTCLASS )
Given an argument which is the name or oid of a known object class,
returns a list of HASHes describing the attributes which are manda‐
tory in the class.
@must = $schema->must ( $oc );
parse ( MESG )
parse ( ENTRY )
parse ( FILENAME )
Takes a single argument which can be any of, a message object
returned from an LDAP search, a "Net::LDAP::Entry" object or the
name of a file containing an LDIF form of the schema.
If the argument is a message result from a search,
"Net::LDAP::Schema" will parse the schema from the first entry
returned.
Returns true on success and "undef" on error.
superclass ( NAME )
Given an argument which is the name or oid of a known objectclass,
returns the list of names of the immediate superclasses.
matchingrule_for_attribute ( NAME, RULE )
Given an attribute name and a matching rule ("equality", "substr",
etc), return the actual rule taking into account attribute super‐
types.
