We have some groups that contain over 250,000 members.
Are there any general tips for improving performance when applications/code
attempts to lookup memberOf values in the ldap?
For example, I have something like ou=SomeGroup,ou=Groups,o=ourOrg.
ou=SomeGroup has over 250,000 memberOf: values. Attempting to modify,
search, insert, etc.. into that memberOf multivalue field takes over 20
seconds per user.
