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.
