Ahh.  OK.  So was the /usr/share/pam-configs/krb5 that I pasted above
what's in libpam-krb5-4.4-1ubuntu1 or not?  If it's not I want to make
sure I am using the one that is shipped.

Will this be backported to Oneiric and Lucid?  It should be.  Lucid is
(still current) LTS and Oneiric is current, despite Precise waiting on-deck.

Title:
  only krb5 results in broken common-passwd

Status in “pam” package in Ubuntu:
  Fix Released

Bug description:
  Using pam-auth-update if I select only krb5 for authentication (that
  is, unselect pam_unix and pam_ldap if installed) I get a broken
  passwd-common pam file:

  # here are the per-package modules (the "Primary" block)
  password	requisite			pam_krb5.so minimum_uid=1000
  # here's the fallback if no module succeeds
  password	requisite			pam_deny.so
  # prime the stack with a positive return value if there isn't one already;
  # this avoids us returning an error just because nothing sets a success code
  # since the modules above will each just jump around
  password	required			pam_permit.so
  # and here are more per-package modules (the "Additional" block)
  password	optional	pam_gnome_keyring.so 
  password	optional	pam_ecryptfs.so 
  # end of pam-auth-update config

  The problem here is clearly that pam_deny.so immediately follows
  pam_krb5.so with no "goto" option specified on the pam_krb5.so line to
  skip the pam_deny.so line if it's successful.
