The conversion from idmap_tdb to idmap_ad can be done by changing
smb.conf. Remove any existing idmap parameters, then add idmap_ad
parameters based on your current environment, e.g (from man page).
[global]
idmap config * : backend = tdb
idmap config * : range = 1000000-1999999
idmap config DOMAIN : backend = ad
idmap config DOMAIN : range = 1000-999999
Changing the idmap backend on a running system is generally not a good
idea, as file ownership and ACLs may change for mapped users.
Idmap caches also need to be purged before restarting winbind. This
can be done by backing up /var/lib/samba/*, then deleting
winbindd_idmap.tdb and gencache.tdb. nscd should also be disabled.
One final caveat, Samba 3.6 idmap_ad uses the rfc2307 gidNumber
attribute assigned to groups for which a user is a member of. It ignores
the gidNumber attribute explicitly assigned user objects.
Cheers, David
