Hi Guys i was wondering could someone clarify whats needed with SAMBA and Windows ad I have setup a samba on rhel6 its not a pdc, it will have to share with an app on the samba server that users will access but the users authenticate through Windows AD when i do net ads join all goes ok if i do wbinfo -u and -u all the users and groups are listed so all appears ok and wbinfo -t works ok too as does net ads info but if i do net rpc trusdom list its blank and net rpc testjoin doesn't work either also in log there is a winbind error intermittently winbindd/winbindd_util.c:289(trustdom_recv) could not recieve trusdom my question is if the samba server is not a pdc and the ads part works, is an rpc trust relationship required ? if it is required does anyone know the meaning of the number in the error .c:289(trustdom_recv) many thanks for any time and help your willing to share :-)
