Error Code 0x26

Definition of TGT/TGS Issue Error Codes codes.

0x26 KRB_AP_ERR_BADADDR Network address in network layer header doesn't match address inside ticket. Session tickets MAY include the addresses from which they are valid. This error can occur if the address of the computer sending the ticket is different from the valid address in the ticket. A possible cause of this could be an Internet Protocol (IP) address change. Another possible cause is when a ticket is passed through a proxy server or NAT. The client is unaware of the address scheme used by the proxy server, so unless the program caused the client to request a proxy server ticket with the proxy server's source address, the ticket could be invalid.
