To implement Authentication Services on a cloned machine, see suggested steps below. Also if you restored from a backup.
If you clone a machine that contains QAS on it you must do the following on the clone:
1) Perform an "unjoin" of the system:
a) if the computer object should remain in Active Directory (for example, if the original machine that was cloned is still an active QAS server), use the command: /opt/quest/bin/vastool -u <AD admin> unjoin -l
b) if the computer object should be removed from Active Directory, use the command: /opt/quest/bin/vastool -u <AD admin> unjoin
This will delete the Authentication Services database files.
2) Rejoin the system: /opt/quest/bin/vastool -u <AD admin> join <yourdomain.com>
(Replace < AD admin> and <yourdomain.com> with appropriate data and remove <>.)
The Authentication Services database files will be recreated and re-populated from data from AD.
Peforming an unjoin will delete database files which will contain out-of-date information from the cloned system.
Peforming a join will create new database files on the newly cloned system and populate with the correct, and up-to-date, data.
