SSDI(4)SSDI(4)NAME
ssdi.conf - Standardized Systems Database Interface (SSDI) configuration
file
SYNOPSIS
/etc/ssdi.conf
DESCRIPTION
This file controls the behavior of accesses to standard system databases,
such as the passwd and group databases. Normally, each database has its
own set of standard access routines. For example, the passwd database
routines are defined by getpwent(3C). When such a routine is called, the
requested information is iteratively searched through various sources.
Usually, all database routines support a standard source which are
compiled-in along with them. For example, the standard source for passwd
is the files source, which implements the database as files. In
addition, the database routines can be made to access sources which are
dynamic.
The file /etc/ssdi.conf contains entries for each database that needs to
access dynamic sources. Entries are separated by newlines, and entries
with a sharp-sign (#) in column 1 are treated as comments. Utmost one
entry is allowed for a database. Each line begins with the name of the
database, followed by a colon, and then a blank separated list of the
names of dynamic sources. Each dynamic source needs to be available as a
Dynamic Shared Object (DSO), and physically present in _SSDI_STD_SRC_DIR
(as defined in /usr/include/ssdi.h ). The name of the DSO for a source
named as foo needs to be foo.so. The maximum number of dynamic source
for a database is limited to _SSDI_MAXSRCS and the maximum number of
characters in the name of a source is limited to _SSDI_MAXSRCNAME (as
defined in /usr/include/ssdi.h ).
Currently only the following databases are supported: passwd, group, and
aux.
Following is an example of /etc/ssdi.conf which lists btree as a source
for both passwd and group databases.
# Sample ssdi conf file
passwd: btree
group: btree
The file btree.so should be present in the _SSDI_STD_SRC_DIR directory.
