Without using shadow, the password is encrypted (hashed?) and stored in passwd, but /etc/passwd needs to be world readable. Anyone with access to the system can grab the hashed passwords and feed them into a password cracking program. Using the shadow password scheme, the encrypted passwords are stored in /etc/shadow, which is readable only by root. That way there is still the required access to /etc/passwd without exposing your password to the world. have you run pwck? The problem sounds similar to the system being set to use ldap or kerberos as the authentication method, however the fix has already been suggested (run authconfig) so i presume that is not it. Have you changed any PAM related files (/etc/security /etc/pam.d)? --- Pete Nesbitt, rhce -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
