Hello Experts,

I am using SAP NW portal 7.0 with SPS15. Datasource is configured as MS ADS. We have successfully configured SSO. with backend R/3 system.

We have also configured SPNego. But while login into system, it gives following error.

Hello,

I see that the Kerberos Client/Server Session Ticket for the AS Java from the KDC is not received by the SPNegoLoginModule.

Please check if you have the right version of the JVM.

Please check this [Link|http://help.sap.com/saphelp_nw04s/helpdata/en/43/4bd58c6c5e5f34e10000000a1553f6/frameset.htm] for further details.
