If a system is configured to use LDAP for authentification with authconfig, logins to local accounts (root for example) will always fail if the LDAP server is unreachable. A possible fix described in bug 118239 has a working pam config for such cases.
Is there any security concern or backward compatibility issue with the proposed configuration?
Is there something that prevent authconfig from being changed to generate such a configuration?
This could possibly affect other network authentification mechanism (kerberos, smb), althought I can't verify it. Also that could possibly fix bug #6371 as well.
