First of all, there is no such thing as Redhat 9 Enterprise -- it looks 
like you're running RHEL3, unpatched.  Secondly, your question has 
nothing to do with ext3, so you will likely get a more helpful response 
elsewhere.  But if I had to guess, I'd say your /etc/pam.d/system-auth 
is corrupted.  You might try reinstalling your pam rpm.
