Description Vijay 2017-05-31 13:42:25 UTC

We have a domain called domain1.local and we created some users for example from user1 to user100... today we found a strange issue with login, normally user logins should work as domain1.local\user1 and his password, but we are able to login with any domain name (anything like adkskasfk\user1) with the domain1.local credentials. In this ticket, I mentioned the version as 4.3.3 but tried with 4.1.17 and 4.3.1 too.

May I know if you come across this, please help us to fix it.

Tried with below version too, same issue. Created a domain like tempdomain.local, joined one system to this domain, i can login from client as tempdomain.local\administrator or vijay.local\administrator.

[root@tempdc01 samba-4.6.3]# /usr/local/samba/sbin/samba -V
Version 4.6.3
[root@tempdc01 samba-4.6.3]#

Please help me to fix this.

It's a known issue in all versions of the Samba AD DC. Stefan Metzmacher right now is working on trusted domain support. When that's done, this bug will also be fixed.
