We are using LDAP to query the member attribute of a PostOffice. Some users that have a functioning mailbox in that PostOffice and are visible as Users of that PostOffice under ConsoleOne are not visible via LDAP as value of the member attribute of the PostOffice.

The user is an admin user with unlimited access, and the eDirectory Object of the missing user is in the same container as another user that is visible.

Has anyone any idea why this might be?
