[Samba] newbie : mapping problem between linux and samba users
Hello
I have a mapping problem between linux and samba users
logged as a domain user steph under windows, I try to update the
password but a message like
"you don't have the right to do that operation" appeals.
Logged as root I can do it.
When I dismiss the synchronisation between linux and windows users,
it works !!
I have also noticed that I can only make mapping between pre defined
windows
with "net groupmap set" and not "net groupmap add sid= unixgroup=
"
which started to fail each time.
(don t know if it s a normal behaviour)
So I have though it was due to a problem in my tdb database file and I
run a check tools giving no problem.
So I put here my mappings :
------------------------------------------------
System Operators (S-1-5-32-549) -> -1
Replicators (S-1-5-32-552) -> -1
Guests (S-1-5-32-546) -> -1
Domain Admins (S-1-5-21-3113648812-2111614216-3829755549-512) -> root
Domain Guests (S-1-5-21-3113648812-2111614216-3829755549-514) -> -1
Power Users (S-1-5-32-547) -> users
Print Operators (S-1-5-32-550) -> -1
Administrators (S-1-5-32-544) -> -1
Account Operators (S-1-5-32-548) -> -1
Backup Operators (S-1-5-32-551) -> -1
Users (S-1-5-32-545) -> -1
Domain Users (S-1-5-21-3113648812-2111614216-3829755549-513) -> users
the logs I have obtained (noticing there is a problem with a share
secret between the window host and the server but which secret ? a
secret for trusted domain ?????? no relation with my problem !!!) :
