Looks like this problem goes back a few versions and I found a patch on
the web the fixed the problem and just wanted to make sure that it got
into the next release:

The symptoms in AIX v5.3 were that when doing an initial kinit on the
server, I get the following message:

kinit(v5): Cannot resolve network address for KDC in requested realm
while getting initial credentials

...and a core dump.

The following patch fixed the problem.  Many thanks to Donn Cave.  I
searched the bug list, but couldn't find this mentioned in results of
the searches and wanted to make sure this was included.

Thanks!
