问题
I am using http://webmoli.com/2009/08/29/single-sign-on-in-java-platform/ for SSO in java.
I have KDC Windows server 2008, in that i have created spn by using setspn command for testsso user. And using testsso@MYDOMAIN.COM as principal in jaas.con.
I have Tomcat server in Windows 7 machine(within AD). In this i have created one servlet as of jsp(from webmoli itself).
I sending browser request for that servlet from 3rd machine Windows XP(within AD).
But i get checksum failed error. Stacktrace as follws-

回答1:
If I remember correctly this error is thrown when the service ticket is decrypted with a different key as it had been encrypted.
ktpass /out c:\tomcat.keytab /mapuser tc01@DEV.LOCAL
/princ HTTP/win-tc01.dev.local@DEV.LOCAL
/pass tc01pass /kvno 0
as described at http://tomcat.apache.org/tomcat-7.0-doc/windows-auth-howto.html is only correct if you have a virgin account 'tc01'... AD will automatically increment key version number stored within AD when 'ktpass' is used consecutively.
