> {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.
