SAP Sourcing and CA Siteminder configuration

Hello experts,

We have followed the directions specified in document http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/b03f5cc3-5e1b-3010-6c84-c54202d5c7b9?overridelayout=t… with exception of Section 2 as we are using Siteminder.

However, we are facing the following issue:

1. When user accesses CLM (https://XXXXXX/sourcing90/fsbuyer/portal/login) they are forwarded to to Siteminder login screen.
2. User logs in
3. User is redirected back to CLM (https://XXXXXX/sourcing90/fsbuyer/portal/login) but is asked to login again using CLM screen.

Any idea regarding what could be happening? OR what additional configuration needs to be done?

We think somewhere between Siteminder and CLM there is some information getting lost and hence the system is asking us to log in again. Do you have any clue regarding what is happening?

Thanks in advance for your time and support.

Best regards,

Isaac
