Julian,
Last thing: did you tried "net cache list", "net cache
flush"? It should be designed to show and flush id map...

Hi,

before we switched to SSSD we've been implementing the ssh authentication
method via Domain using winbind+samba.
Version installed on our machines is (still) 2:4.1.6+dfsg-1ubuntu2.14.04.13. So
far everything has been working fine, however
after we had to change a user's logon name in the domain he can't login
anymore. auth.log shows still his old username followed by "from <IP>
not allowed because none of user's groups are listed in AllowGroups". I
searched several websites for a solution but only found recommendations on
deleting
the winbind cache at /var/lib/samba. However this didn't fix the problem.
When I do a grep using getent passwd on the users NEW name, it shows up.
So actually the domain controllers is delivering the correct username.

Is this a known bug in version 4.1.6 or can I solve this any other way without
running a package upgrade on a production machine?

Cheers
Julian
