Probably not a misconfiguration. Perhaps thinking of it this way will help :
Consider 500,000 ldap operations of the form
and less than 500,000 ldap operations of the form
Depending on the depth of your group nesting and average number of
memberships per group, the bulk operations should be faster when
provisioning everything. However, for a large group, bulk operations
are slower when provisioning a single membership (because the psp
reads everything when doing a diff). Directory performance may vary
based upon indexing and referential integrity too.
