Before I post to bugzilla, I was wondering if anyone could advise on this particular problem. I have a custom pam module to handle authentication on my system. I can login via console,ssh,etc but I can not login via gdm. I've turned on debugging in gdm and can not find anything useful. The only difference I can see is the addition of pam_env.so between 8.0 and 9 (everything worked fine in 8.0). Any ideas? the authentication is a 1 time password, but, the password is not even being expired from the auth server so the authentication request is not even happening. very weird. tom
