Fix OpenChange server code and access to Samba4 databases.
Starting with samba4-alpha9, there is no more configuration.ldb or users.ldb.
All information can be accessed through a single access to SamDB and configuration records
accessed through ldb_get_config_basedn.
The following implementation has been tested and is working with:
- mapiprofile profile creation
- openchangeclient --mailbox
- Outlook 2003 account creation
- Outlook 2003 mailbox opening
