Ho provato per diversi giorni per farlo funzionare. Finora sto ottenendo l'errore Cannot find key of appropriate type to decrypt AP REP - AES256 CTS mode with HMAC SHA1-96:, sebbene a volte con una modifica di ktpass l'errore si riferisca invece ad AES128.
Ho letto "Capitolo 2. Come configurare SSO per JBoss EAP con Kerberos" e ho letto molti (molti, molti) post. Inizialmente stavo usando Tomcat 8 con il progetto SPNEGO sourceforge e l'ho ottenuto lavorando con il mio progetto GWT (2.8.2). Nessuna fortuna ancora se il JBoss. Nel ktpass di seguito ho provato / kvno 0 e 1, 2, 3, 4 e omettendolo del tutto, ma non ha fatto alcuna differenza, tranne per il fatto che (credo) il messaggio di errore si è lamentato (alternativamente) di AES128 e quindi 256. Ottengo questo errore quando si prova con Firefox. Se uso IE 11 non capisco, richiede un utente e una password (che è stata una sorpresa). Se inserisco le mie credenziali non dà l'errore, dice solo:

Refreshing Kerberos configuration

Will use keytab
