Title:
  After failed auth, subsequent auths in same context fail

Status in “krb5” package in Ubuntu:
  Incomplete
Status in “krb5” package in Debian:
  Fix Committed

Bug description:
  MIT Kerberos 1.10 (including pre-releases and betas) exposed a bug in
  the tracking of preauth mechanisms such that, if an authentication
  fails after preauth was requested, all subsequent preauth-required
  authentications in the same Kerberos context will also fail.

  This breaks password change when credentials have expired, and also
  breaks try_first_pass functionality in Kerberos PAM modules.

  Upstream has fixed this problem in their mainline with commit 25822.
