[Bug 874130] Re: Canonicalize fallback only works for different realm (MITKRB RT #6917)

** Changed in: krb5 (Ubuntu Oneiric)
       Status: Triaged => In Progress

** Changed in: krb5 (Ubuntu Oneiric)
     Assignee: (unassigned) => Steve Langasek (vorlon)

** Description changed:

+ SRU justification:
+  krb5 1.9.1 breaks interoperability with older KDCs.  If you have a Kerberos realm with one of these older KDCs that does not implement the "canonicalize" option, oneiric's will be unusable as a Kerberos client for this realm.
+ 
  See RedHat bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=713518.
  
  Quoting:
  Certain versions of the KDC software (included for example
  in Red Hat Enterprise Linux 2.1 and 3) reject requests,
  which include KDC options the software does not recognize,
  and do not support the "canonicalize" option. When a client
  was configured to use one of these versions of the KDC
  software, the client failed to obtain credentials for
  authentication to other services. This interoperability
  regression was introduced in the update to Red Hat
  Enterprise Linux 6.1. With this update, an upstream patch
  has been provided to fix this bug.
  
  I have applied the patch provided on this bugzilla page, and this fixed
  the problem.
