>             Project: WildFly Elytron
>          Issue Type: Bug
>            Reporter: Josef Cacek
>            Assignee: Farah Juma
>            Priority: Blocker

> Invalid initial token is used on server for *GS2-KRB5-PLUS* SASL mechanism. The  {{Gs2SaslServer}} uses a GSSContext to accept the token. It expects AP_REQ is comming (*{{AP_REQ_ID=256}}*), but the incomming tokenId has value *{{669}}* (value of first 2 bytes of token body).
> Setting blocker as this mechanism is required by EAP7-530 and EAP7-142.
> Following exception is thrown:
> {noformat}
> GSSException: Defective token detected (Mechanism level: AP_REQ token id does not match!)
