[Samba] winbind and smb tries to auth as pdc$ rather than local name when using ADS

This specific instance is intended to host shares for which users
authenticate with their AD credentials, the normal authentication for
the system works fine and so does joining the domain. As mentioned
earlier initializing kinit and wbinfo returns the expected results and
the server shows up as a member in AD.

I'll try to replace the workgroup with the realm-data.
