Editing LDAP Idle Time Limit on the ContentDirector
During authentication, the connection between the ContentDirector and Open Directory server
might time out. This occurs when the LDAP idle time limit on the Open Directory server is less
than the LDAP time limit on the ContentDirector. By default, the ContentDirector is set to 3600
seconds, while the Open Directory server is usually set to 300 seconds.
NOTE: The idle time limit on your ContentDirector may be different from the default value.
To prevent or correct the errors, you must change the idle time limit on the ContentDirector to a
value lower than the idle time limit on the Open Directory server.
To edit the LDAP idle time limit:
1. First, determine the LDAP idle time limit on the Open Directory server:
a. Open
/etc/openldap/slapd_macosxserver.conf on the Open Directory server and find the
idletimeout value.
2. Log on to the ContentDirector and do the following:
a. Open
/etc/ldap.conf and find the value for idle_timelimit.
b. If this value is greater than the idletimeout value on the Open Directory server, change
idle_timelimit to 100.
3. Repeat step 2 for each ContentDirector in your MediaGrid cluster.
