{code}

*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.
