[krbdev.mit.edu #7118] Possible kadmin bug in Ubuntu 12.04

[Brian F Knoll via RT]

I have found what I think might be a kadmin bug in Kerberos 5 as shipped in Ubuntu 12.04.

If I create an Ubuntu 12.04 installation in a VM, then install the krb5-kdc and krb5-admin-server packages, I can create a test realm.  Once I do this, I can use kadmin.local to add principals, and I can kinit to those principals.  That all works fine.

However, when I try to use kadmin to connect to the admin server, it hangs for a few minutes, then fails with an "Unspecified GSS failure: clock skew too great" error.  This is even when I use kadmin to connect to the same machine, meaning that the clock would by definition have to be correct.  I started to file a bug report on Ubuntu's Launchpad site but it mentioned this email address, so I thought I would check here first to see if I should be reporting the bug here instead of on Launchpad.  This all works fine if I use an Ubuntu 10.04 VM instead of an Ubuntu 12.04 VM.

If I should, instead, report this bug to Ubuntu (if it is a packaging error, perhaps), then please let me know so I may do so.

Thanks,
Brian
