Valid question.
The target server, let's call it nfs03.nix.mds.xyz shares a path via
both CIFS and NFS. The said server, nfs03, is Kerberized via SSSD to a
set of FreeIPA servers. The FreeIPA servers in turn have a trust with
the AD DC domain mds.xyz .
nfs03 <-> FreeIPA <-> AD DC
So joe at mds.xyz is an AD user presented via FreeIPA on nfs03.
[root at nfs03 samba]# id joe at mds.xyz
uid=166602204(joe at mds.xyz) gid=166602204(joe at mds.xyz)
groups=166602204(joe at mds.xyz),1843300089(domain-users)
[root at nfs03 samba]#
Running
id joe
doesn't work of course. Doesn't exist. mds.xyz is the AD domain.
There are other domains and other users on those different domains, such
as drew at nix.mds.xyz, who doesn't exist in AD and is only local to Linux
servers. We also need to distinguish a user1 at mds.xyz vs a
user1 at nix.mds.xyz for example. So need to use the domain, at least for now.
Using joe won't work in samba since it checks the OS to verify the user
exists. So need to use joe at mds.xyz however Samba, rightly so, splits
this string up into what it things is the user, 'joe' and host
'mds.xyz'. I'm looking for a way to suppress this so it doesn't split
up joe at mds.xyz .
"Sadly this really appears to be is a client issue. You see there the
string Samba gets, so by the time Samba tries the process it the @ is
already interpreted and the string split.
Sorry!

Yeah, wondering if there is a way to tell Samba NOT to split that up and treat joe at mds.xyz as a single user. This works fine in Win 10 so I agree, it's probably a client SMB configuration issue but would like to know exactly what that config issue is.
