*Cause*
This is caused by having a _custom/unexpected_ identity in the user-supplied
Kerberos descriptor that is not in the Kerberos descriptor from the initial
stack.
*Solution*
Ignore the _custom/unexpected_ identity since the user must have added that
manually and it is expected that it should remain untouched after the upgrade
process.
