Centos 7 joined to 2012 R2 AD domain
Joined to AD domain with realm join and now I can ssh in as any domain user (ssh server -l firstname.lastname@example.org)
I can also login to the local console via email@example.com as well.
I want to only allow certain domain groups to ssh in so I added this to the bottom of /etc/ssh/sshd_config:
(serveradmins is an AD security group)
But that doesn't seem to work. Users in the serveradmins group cannot login and I see these messages in /var/log/messages:
I also tried
I think ssh or something is messing with the password because preauthentication failure errors are usually incorrect password problems (according to microsoft)
I should say I can still login locally as firstname.lastname@example.org without issues.
Edit: OK so I have achieved what I wanted to accomplish with pam_access by enable the module for sshd and then writing this to access.conf:
+ : (LAB\serveradmins) : ALL - : ALL : ALL
Seems like pam_access is the way to go as it is more uniform, but I'd still like to know where sshd_config is falling down.
