Comment 17 for bug 571572

To answer questions about getting an update into 12.04, we need (from https://wiki.ubuntu.com/StableReleaseUpdates):

An impact statement which explains who this bug affects (use cases), why this is a problem and why we need an update in 12.04 for it.
A test case with exact steps to reproduce the problem, so that we can verify any backported fix.
Confirmation that this is fixed in the development release (Raring).
A patch to fix this issue in Precise. Ideally this would be a pointer to the upstream commit and apply cleanly.
Discussion of possible regressions to existing users, particularly any change in behaviour that an existing user not affected by this bug might get angry about, and areas where a regression is likely to be found if one does exist so that the SRU verification team can try and find them.
All of this information gathered together in one place for the SRU team to review.

I am familiar with Kerberos and have spent my share of time debugging DNS-related Kerberos issues, but I'm read through this bug and although I have some idea I don't feel that I'm completely clear on answers to these questions. If somebody can help with this "paperwork", point out the upstream commit to cherry-pick and there is consensus on all of this, I think there's enough here to warrant an update to 12.04.
