That's definitely not supposed to happen.  Against an MIT KDC, I seeonly one try, followed by:
  kinit: Password incorrect while getting initial credentials
However, we do have at least one other report of looping with krb5 1.7'skinit:

so there is probably an interoperability issue against AD.  I will seeif I can replicate the issue; if I can't, a detailed packet trace fromyou might be sufficient.
