If wbinfo is tweaked in order to avoid bug 6617 querying users and groups in samba do not work.
ie. wbinfo -p works
but wbinfo -u gives
"Error looking up domain users"
In the logs on the server this messages appear:
Failed to setup credentials for account TEST$: NT_STATUS_UNSUCCESSFUL
Kai is the winbind guy.
Which wbinfo and which winbind server is that? The error output looks like this is a S4 winbind, are you running an S4 wbinfo?
Yes it's a wbinfo4 with a s4 server, once I tweaked the code to make it point to the good pipe.
It seems that something was rotten in my samba4 provision, a freshly provisionned s4 just work ...
