ldapcd.conf
ldapcd.conf(4) Kernel Interfaces Manual ldapcd.conf(4)
NAME
ldapcd.conf - Configuration file for the single sign-on daemon.
SYNOPSIS
# comment_string parameter: integer identifier: string identifier: "quoted_string,quoted_string,..."
DESCRIPTION
The ldapcd.conf file stores the current configuration of the Windows 2000 Single Sign-on daemon (SSO). The information stored in the file
is specified when you configure Windows 2000 Single Sign-on and is not normally changed.
The ldapcd.conf file also contains the default operating parameters for the daemon which you can tune for performance. You might need to
tune performance if users wait a long period of time for the UNIX server system to respond.
To tune the Windows 2000 SSO software, use a text editor to modify the values of the caching parameters as follows: The number of open con-
nections that the caching daemon makes to the active directory. Increasing the value of this entry opens more connections to the active
directory, however this consumes more file descriptors and increases the load on the active directory. Typically, 4 connections are ade-
quate for a workstation and 15 connections are adequate for a server.
Default: 4 connections The maximum number of user entries to store in cache. Increase or decrease this value as the maximum number
of users increases or decreases.
Default: 500 entries The maximum number of seconds to cache a user entry. Increasing this value increases performance because a
user's entry is readily available in the cache. If you delete a recently used user account, its entry remains in the cache for the
amount of time specified by this parameter.
Default: 900 seconds. The maximum number of group IDs to cache. Increasing this value increases performance because group IDs are
readily available in the cache.
Default: 100 group IDs The maximum number of seconds to cache group IDs.
Default: 900 seconds
Using a Revised Configuration
If you change the value of a cache parameter in the /etc/ldapcd.conf file, you must enter the following command to read the new configura-
tion and restart the daemon: # /sbin/init.d/ldapw2k restart
EXAMPLES
The following example shows a typical configuration file: # connections: 4 pw_cachesize: 500 pw_expirecache: 900 gr_cachesize: 100
gr_expirecache: 900
