I have removed this comment. With the addition of the 'ldap replication

This will work fine. Samba will talk to the master for updates. Set
'ldap replication sleep' to the amount of time you expect the slave to
take to catch up to reality. (Oh, and I know that's dody, but better

In the configuration, if the master cannot be reached, the slave will be
contacted as a read-only backup. Updates will fail.
