I'm trying to find all the steps necessary for successfully changing a username
on our system, and it appears that when I try to rename the corresponding
principal using kadmin, the principal just disappears (see the transcript
below).
I'm using 1.12 as distributed with Ubuntu 14.04.1 LTS (Trusty), all updates
installed. The KDC stores its data in an openldap directory.
I can provide more details about the setup if needed. For now I'd like to know
if I'm missing anything obvious, and if other people can reproduce the
behaviour I see – that should be easy to check.
Best,
Rasmus

Try to rename the principal:
kadmin.local: rename_principal rbhtest3 rbhtest4
Are you sure you want to rename the principal "rbhte...@intomics.com" to
"rbhte...@intomics.com"? (yes/no): yes
Principal "rbhte...@intomics.com" renamed to "rbhte...@intomics.com".
Make sure that you have removed the old principal from all ACLs before reusing.
Check that the principal cannot be found by its old name:
kadmin.local: get_principal rbhtest3
get_principal: Principal does not exist while retrieving
"rbhte...@intomics.com".
Try to find the principal by its new name:
kadmin.local: get_principal rbhtest4
get_principal: Principal does not exist while retrieving
"rbhte...@intomics.com".
