The ldap_cachemgr daemon must be running and functioning correctly at all times. Otherwise, nothing works. There are two ways to check if ldap_cachemgr is running.
Use ps -ef.
# ps -ef | grep ldap_cachemgr
Pass the -g option to ldap_cachemgr.
This causes it to dump the following status information, which is useful when you must diagnose a problem.
# /usr/lib/ldap/ldap_cachemgr -g
