KDC 1.15.1 - addprinc random failure

[Yegui Cai]

Hi all.

I run KDC 1.15.1. At the host, I use kadmin.local to add a principle. Very
strange that my first attempt failed silently while the second attempt
succeeded. Here are the steps:

[root at gamma-hactive ~]# kadmin.local
Authenticating as principal hdfs/admin at EXAMPLE.COM with password.
kadmin.local:  addprinc yegui
