3.6.0 Domain trusts broken

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

Since the winbind refactoring in Samba 3.6.0, interdomain trusts between Samba servers seem to be broken in that being able to resolve or modify file permissions on the other domain work only very intermittently (eg about once out of 10 tries). This is regardless of whether I use idmap_rid or idmap_ldap as the backend.

I set up two 3.6.0 domain controllers with an XP client attached to each, and trying to add permissions from the trusted domain by choosing the domain and hitting the "Add" then "Advanced" buttons and then the "Find Now" mostly brings up a password prompt - any credentials entered here still cause the listing of users/groups/security principals to fail with a "Login failure: unknown name or bad password" dialog. However I can still log in to either domain from XP with no issues.

The smb.conf on one of the servers is as follows, the other server is the same apart from the domain being "TESTDOM2" and wins server = <ip of PDC> rather than "wins support=yes".

Any help is much appreciated.

Thanks,

Alex
