Error description

  • When a Kerberos token exists in the Microsoft Windows native
    ticket cache, Java security has access to the token, so the
    WS-Security token generator should be able to pick it up and
    generate it. However, WS-Security is unable to pick up the
    token from the Microsoft Windows native ticket cache.

    *                      does not pick up tokens from Microsoft  *

    ****************************************************************
    The WS-Security Kerberos token generator
    KRBGenerateLoginModule is not picking up a Kerberos token that
    is available in the Microsoft Windows native ticket cache.
    When there is a token available in the Microsoft Windows native
    ticket cache and a Kerberos token is not available through
    other methods (username and password in callback handler or
    Kerberos token on runAs subject), an error similar to the
    following may occur:
    [20/07/2012 16:52:20:241 EDT] 00000000 3
    ecurity.wssapi.token.impl.KRBGenerateLoginModule
    idForServiceTicket is null.
    [20/07/2012 16:52:20:241 EDT] 00000000
    ecurity.wssapi.token.impl.KRBGenerateLoginModule Error:
    CWWSS7292E: Failed to login for Kerberos AP_REQ token
    generation due to exception java.lang.NullPointerException
    from Kerberos Token Profile processing runtime.
    CWWSS7292E: Failed to login for Kerberos AP_REQ token
    generation due to exception java.lang.NullPointerException
    from Kerberos Token Profile processing runtime.
    

Problem conclusion

  • The WS-Security runtime dit not recognize that there is a
    ticket in the Microsoft Windows native ticket cache.
    
    The WS-Security runtime is updated to access a Kerberos token
    in the Microsoft Windows native ticket cache.
    
    The Kerberos token generator will use the following priority
    when generating tokens:
    
    1) Username and password specified on the callback handler
    2) Ticket in runAs subject on the current thread
    3) Ticket in Microsoft Windows native ticket cache
    
    The ticket will only be used from the Microsoft Windows native
    ticket cache if there is no username and password specified in
    the token generator's callback handler, and there is no
    Kerberos ticket on the current thread's runAs subject.
    
    The fix for this APAR is currently targeted for inclusion in
    fix packs 7.0.0.27, 8.0.0.5, and 8.5.0.2.  Please refer to the
