On a rawhide system that uses ldaps for user info and krb for auth, the nss_ldap-207-7 update kills non-local login. Reverting to nss_ldap-207-6 from FC1 updates seems to fix the problem (I also fixed a requisite -> required in /etc/pam.d/system-auth but it woudln't let me log in till I downgraded the package) On a related problem the CLI auth setup does not enable to unselect ldap auth if ldap user info is selected (the gui part does)
Still there with nss_ldap-207-7.1
Fixed in 212-1.
