When the number of objects in a tree is very large (greater than 100,000), users can experience substantial LDAP authentication delays when accessing Samba on an OES server.
To reduce the search time, you have the following options:
Set the object cache high enough that all the objects being searched are cached in memory. For more information, see the NetIQ eDirectory Tuning Guide.
Index the objectClass attribute (the attribute that is compared during the LDAP search). For more information, see Index Manager
in the NetIQ eDirectory Administration Guide.
Add an eDirectory replica to the server where the search is taking place. For more information, see Adding a Replica
in the NetIQ eDirectory Administration Guide.
