I have painstakingly gone through a number of TID's and other sources including 3280667 with no luck. I have a gone through the LUM enabling steps and get the appropriate response when running "id username". I tried modifying the "/etc/pam.d/login" file and adding the "auth required /lib/security/pam_nam.so". No luck. I tride TID 3994289 and copied the /etc/pam.d/gdm" file to "/etc/pam.d/gdm.original" and then modifying the "/etc/pam.d/gdm" file to include:

account sufficient pam_nam.so
password sufficient pam_name.so
session optional pam_nam.so

Now I'm getting the error in "messages" that "gdm[1701]: Couldn't authentidcate user"

I tried TID 3806971, but no better luck.

What have I done wrong? How can I fix it?

Thanks in advance!
