As mentioned in the thread, the problem is due to the name-type field not being set in the PA-TGS-REQ, which is a required field for read only domain controller (RODC), without this feild KRB5KRB_AP_ERR_BAD_INTEGRITY will be returned.

After renewing the ticket using "kinit -R", it can be observed in a network trace, KRB5KRB_AP_ERR_BAD_INTEGRITY error is returned when requesting the service ticket.
