The MMP can cache results of user searches. The
ldapcachesize option defines the number of cache entries;
ldapcachettl (available under
vdomain) defines the length of time the entries are preserved in seconds. Lower values will reduce performance, but result in faster recognition of LDAP user entry changes. Higher values will increase performance, but result in delayed recognition of LDAP user entry changes.
Note that setting
ldapcachettl smaller than
authcachettl causes the entire user entry to expire, thereby also expiring the user authentication information in that user entry.
The default value is: 900
