I don't know much Fedora these days but here are some thoughts:

1) Can't enter a password: your login program is corrupted/hosed because
   of some inconsistent libc library versions (some with old libc,
   some with new libc)

2) My guess is your whole system is in an inconsistent state and that
   most programs will have problems because of old vs. new libc

3) Use a fedora rescue disk to force a complete update of all installed
   packages so everybody uses the new libc.
