Attributes for Ex5.5 Mailboxes : Hide-From-Address-Book
This is a boolean TRUE/FALSE value which determines whether the object is hidden in the global address book or not.
Hide-From-Address-Book
| LDAP name | Hide-From-Address-Book |
| Data type | Boolean |
| Multivalue (Array) | No |
| Heuristic | 20 => Replicated between sites, no operational attribute |
| Access category | Admin access only |
| Ex55 Database name | Hide-From-Address-Book |
If this attribute is set to TRUE, you will see the mailbox in the Exchange 5.5 admin utility only if using the option "View -> Hidden Recipients".
Even more strange: Hidden recipient objects are invisible for an LDAP client even in the first moment. For reading and accessing such objects in an LDAP session, you have to use the administrative bind logon when connecting to the LDAP Exchange 5.5 server. The credentials for the neccessary OpenDSObject() function have to be in this notation:
cn=<Username>, dc=<Domäne>, cn=admin
Attention: The connect with an administrative bind has a strange side effect:
If searching for LDAP objects (for example you search for all objects in
one container), the system also returns all deleted objects in case that
these objects are still existing as thombstones in the directory database.
You might use an LDAP filter with the attribute Is-Deleted.
