[Samba] Request for credential for just one user on one specific machine when using FQDN




Hi,

I have deployed a new file server (Samba version 4.6.2, CentOS 7) which
is running as a member of an AD domain (The DCs are both Windows server
2012, forest and domain level is 2012 as well). I'm using the AD backend
to store SID/UID mappings.

So everything is working fine except for one specific user on one
specific workstation (Windows 10) who can only access the file server
with \\IP_Address, using the name of the machine or the FQDN gives
access denied and prompt for authentication.

The same domain user on different machines (Tested windows 10, 8, 7,
XP)  is working fine and every other user I tested on the problematic PC
is also working without issues.

Going through the logs I found that when the user connect with the FQDN
Samba is apparently trying to map [Full Name]@[DOMAIN] instead of
[Username]@[DOMAIN]

Thanks for any advice, maybe is not even a problem with Samba.
