The slapd.conf file is the central source of configuration information for the OpenLDAP standalone server (slapd), the replication helper daemon (slurpd), and related tools, such as slapcat and slapadd. As a general rule, the OpenLDAP client tools such as ldapmodify and ldapsearch use ldap.conf (not slapd.conf) for default settings.
In the tradition of Unix configuration files, slapd.conf is an ASCII file with the following rules:
Blank lines and lines beginning with a pound sign (#) are ignored.
Parameters and associated values are separated by whitespace characters (space or tab).
A line with a blank space in the first column is considered to be a continuation of the previous one. There is no need for a line continuation character such as a backslash (\).
For general needs, the slapd.conf file used by OpenLDAP 2 can be broken into two sections. The first section contains parameters that affect the overall behavior of the OpenLDAP servers (for example, the level of information sent to log files). The second section is composed of parameters that relate to a particular database backend used by the slapd daemon. It is possible to define some default settings for these in the global section of slapd.conf. However, any value specified in the database section will override default settings.
Here’s a partial listing that shows how these two sections look:
