Hi,

I'm trying to authenticate with active-directory users (Windows Server 2008 R2) on my Ubuntu 16.04 workstation.

I used the steps in "SSSD and Active Directory" from the Ubuntu documentation.

Adding the computer-account to active-directory worked.

Running id <active-directory-user> also returns the correct active-directory-groups the user is in.

But I can't login with active-directory-user. 

content of /var/log/auth.log:

pam_sss(login:auth): authentication success; logname=LOGIN uid=0 euid=0 tty=/dev/tty1 ruser= rhost= user=frsc

pam_sss(login:account): Access denied for user frsc: 4 (System error)


output of "service sssd status":
