SSO problem by Redirecting URL between Portal and GRC 5.3 SP5.

I am working on SSO between Portal 7.0 and GRC 5.3 request URL. We have SPNEGO / LDAP configured in Portal.

After following SAP NOTE 1252589, I install redirect application in Portal server and use redirect application to access GRC URL. URL link is

http://<Portal hostname>:50000/RedirectApp?redirectURL=http://<GRC hostname>/AE/index_apr.jsp

After creating URL iview with this link, the iview shows errors as follows:

" Application error occurred during request processing.

Details: com.sap.engine.services.servlets_jsp.server.exceptions.WebIllegalArgumentException: Cannot redirect to "null" location."

If I run this URL link from IE directly, SSO does NOT work and GRC log-in screen shows up.

But SSO is working If I turn off "Integrated Windows Authentication" in IE.

Please give me some advice. Thanks.

    Hi,

    Have you checked the UME Data configuration file.

    Note 718383 may also help?

    The problem is resolved by myself.

    1) Iview error is resolved after creating URL iview with new window.

    2) SAP document missed the log-in module configuration for RedirectAPP.

    3) It is not necessary to configure SPNEGO in GRC.

    4) Make sure there is only one ticket issued from Portal. I had two tickets from Portal since one iview is hard coded to the production system. It caused the problem.

    Thanks.

    I am also trying to do the exact configuration for our EP. Could you elaborate on Step 2) in your reply that mentioned SAP forgot to include the configuration for the login module? Would you be able to share the configuration that is necessary?

    Thanks,

    Same problem here...

    GRC AC 5.3 SP 10.-

    Redirect APP over GRC (not portal environment)

    Login module changed in redirectapp

    SSO succesful for RAR an SPM, not for CUP and ERM.

    "null" erorr shown... authentication works, but not the redirection...

    Thanks
