Default PAM authentication failure

My PAM module seems to work right but it fails in authentication. Althought it can't authenticate, the session module works and the software who uses it executes well.

For example, when I login through "gdm" using pam to authenticate against an ldap server
/var/log/auth.log shows
Quote:
pam_unix(gdm:auth): authentication failure; logname= uid=0 euid=0 tty=:0 ruser= rhost= user=myuser
pam_unix(gdm:session): session opened for user myuser by (uid=0)
Any ideas?

Try upgrading system and kernel and see if that can fix the issue. Did you made any changes to pam config file?

In fact, that was part of the problem. On Ubuntu 7.10 works right but on Ubuntu 8.10 shows that message.
