KFW does not perform password validation. The tickets obtained by KFW are not used as a sign of permission to logon to the machine. The tickets can only be considered validated after they have been used to authenticate to a service that has decrypted the portion of the ticket encrypted in the service principal's long term key. If you are using the ticket as part of a password validation, you must have a key for a service principal and you must obtain a service ticket for that principal and validate that you can decrypt it with the service principal's long term key.
