Re: Nifi authentication through Kerberos issues
The important part is:
Caused by: sun.security.krb5.internal.KrbApErrException: Message stream
modified (41)
The code that produces this exception looks like this:
// Reply to a renewable request should be renewable, but if request does
// not contain renewable, KDC is free to issue a renewable ticket (for
// example, if ticket_lifetime is too big).
if (req.reqBody.kdcOptions.get(KDCOptions.RENEWABLE) &&
!rep.encKDCRepPart.flags.get(KDCOptions.RENEWABLE)) {
throw new KrbApErrException(Krb5.KRB_AP_ERR_MODIFIED);
}
From googling, a possible solution here:

Re: Nifi authentication through Kerberos issues
Posted by Derek Richardson <dj...@gmail.com>.
That was it! I pulled out the line "renew_lifetime = 7d" and it worked!
Thank you so much.
