Kerberos Login seems to work, still gets rejected

873424 Newbie
Currently Being Moderated
I've got a Java client app and a Java server app, and I'm trying to authenticate to the server via Kerberos. The client basically uses Apache http-components and SPNEGO to make a HTTP GET call, but I always get 401 Unauthorized as a result.

I can not spot the error in the Kerberos login sequence below, maybe you guys can:

    Everything looks fine on the client side. Can you find some server side log? Maybe the server's service name is not HTTP/alf-test.server.com? Or you keytab file on the server side has something wrong?

    Hello,

    I don't know whether you have already solved your Kerberos issue, but I can give you some solution.
    Recently I've migrated JRockit version to jrockit-jdk1.6.0_26-R28.1.4-4.0.1 and my settings stoped working also. Almost the same problem you have described.
    When I've rollback that change, means switch back to previous JRockit, which is jrockit-jdk1.6.0_20-R28.1.0-4.0.1, everything started working again.

    So... try different JRockit version. I'm still trying to solve problem with new JRockit b/s it solved other my problem.

    Rgds,
    Waldemar Thiel

    ps. most funny is that problem is on PROD environment, but new JRockit and Kerberos (SSO) is working fine on PRE ;-)
