[Samba] Accessing Samba domain member shares from trusted domain
Ok well I have that setting you mention I just can't map my trusted AD account in the trusting domain on my Linux Samba domain member I can't see any users in the trusted domain actually wbinfo -u --domain=TRUSTED returns nothing at all I did see an article that suggested the POSIX attributes for AD users need to be published to the AD global catalogue before they can be accessed in the external trust domain? My Wintel AD guys says the attributes are not published. But still I might expect to see users listed with wbinfo even if their POSIX attributes are not allowing use as a UNIX account?

I would make sure to use "winbind scan trusted domains = yes" and ignore the wbinfo -m and --online-status stuff. As a domain member, we should only ever talk to a DC of our primary domain and with "winbind scan trusted domains = yes" that's exactly how we will behave. Trusted domains are added to our internal list of known domains when a user from a trusted domains authenticates and will then start appearing in the wbinfo commands, but not otherwise. -slow -- SerNet Samba Team Lead https://sernet.de/ Samba Team Member https://samba.org/ SAMBA+ packages https://samba.plus/ ---------------------------------------------------------------------- This is an e-mail from General Dynamics Land Systems.

We're not allowed to talk to a DC in the trusted domain to query a user list. That can't be done via a trust route.> I did see an article that suggested the POSIX attributes for AD > users need to be published to the AD global catalogue before they > can be accessed in the external trust domain?

You have to use a different idmap backend. You could also use idmap_rfc2307 to point at an LDAP server that does allow connections and also stores the mappings. -slow -- SerNet Samba Team Lead https://sernet.de/ Samba Team Member https://samba.org/ SAMBA+ packages https://samba.plus/ -------------- next part -------------- A non-text attachment was scrubbed...
