Failed to start session

[Nathan-plug]

Hi all,

I am having a problem that is running me around in circles.

I have an open directory server providing authentication for my users 
and use Salt to manage my configurations.  I have a workstation that I 
recently reloaded with Ubuntu 14.04 and everything looked great through 
Salt but I have a problem logging into the machine.  This is where it 
gets weird.  I have 2 sessions available, lightdm and xfce.  Lightdm is 
default and existing users cannot log in (it says "failed to start 
session") however, if I change to xfce or log in on a terminal I can log 
in.  After logging in via xfce or terminal, I can then log in as an 
existing user.
It is a little more weird when I decided to stop bugging one of my users 
during troubleshooting and created a new test account and was able to 
log in without issue.
The only thing I can see in my logs are:


auth.log:Jul  7 13:33:09 ops1 lightdm: pam_succeed_if(lightdm:auth): 
requirement "user ingroup nopasswdlogin" not met by user 
"brokenUsername"
auth.log:Jul  7 13:33:13 ops1 lightdm: pam_unix(lightdm:auth): 
authentication failure; logname= uid=0 euid=0 tty=:0 ruser= rhost=  
user=brokenUsername


lightdm/lightdm.log:[+79.51s] DEBUG: Session pid=5740: Authenticate 
result for user brokenUsername: Success
lightdm/lightdm.log:[+79.51s] DEBUG: Session pid=5740: User 
brokenUsername authorized

I though it had something to do with home directory creation but like I 
said, the new test account I created is working fine.

Any thoughts are appreciated.

Thanks

Nathan
