[Samba] Interdomain Trust, wbinfo works on both servers, getent doesn't work on one server
Hi I have a problem with an interdomain trust where on the PDC for DomainA, everything works perfectly. getent returns local and DomainB usernames. On the PDC for DomainB, it's DomainB works fine, but getent only returns local usernames and groups, it doesn't return the usernames or groups for DomainA. wbinfo -u and wbinfo -g work fine and return all DomainA's usernames and groups. This means that I can set permissions for DomainB staff on DomainA, and they can successfully map shares and access files on DomainA. I can't set permissions for DomainA staff on DomainB, and DomainA staff cannot access DomainB using their own username and password :-( I initially tried with a single WINS server on PDCA, then local WINS servers with static pointers to the other Domain and PDC. The behaviour was the same as above for both configurations of WINS. Given that wbinfo is working, is there a misconfiguration or a corrupted database somewhere that is stopping getent working?
