Issue with Kerberos authentication using API / MSLSA ccache type

Are you sure you are using MIT Kerberos?  Because based on the messages
below it sure seems like you actually using the Java Kerberos library
and I was under the impression that was it's own thing.  Also, the
debug messages you show are not ones typically generated by MIT Kerberos.
E.g.:

Java config name: C:\ProgramData\MIT\Kerberos5\krb5.ini
Loading krb5 profile at C:\ProgramData\MIT\Kerberos5\krb5.ini
Loaded from Java config
>>> KdcAccessibility: reset
>>> KdcAccessibility: reset
Acquire TGT from Cache
Principal is MYUSER at NZSQA.IBM.COM
null credentials from Ticket Cache

Nothing I can find in MIT Kerberos generates these messages.  MIT
Kerberos debug messages (which are generated by setting the KRB5_TRACE
environment variable) look like this:

[1613] 1732387726.184428: Response was from primary KDC
[1613] 1732387726.184429: Processing preauth types: PA-ETYPE-INFO2 (19)
