[Samba] Fileserver upgraded from 4.1.17 to 4.2 dosen't authenticate users

Wed Apr 20 10:22:18 UTC 2016

Hallo

The Debian team was unable to keep 4.1.17 patched, so they switched to
4.2 branch. However, fileserver at this version (4.2.10) is no more able
to communicate with DC at samba 3.5 (unable to authenticate users - got
weird rpc version error in log)

Please, are there any parameters that could make this work for a while now?

Sincerely

Peter
