Re: [suse-security] /etc/shadow unchanged but password not valid anymore

I'm facing something like a miracle: On a SuSE 9.3 PC from time to time for some users the login is denied but the accounts are not set up with expiration nor are they disabled and the /etc/shadow is unchanged (compared with diff and md5sum with a copy of the file).

Maybe /etc/nsswitch.conf or /etc/pam.conf was modifed?
