Hi
I am planning to do SSO configuration from multiple Ep Systems(EPDev,EPProd) with same r3.is there any configuration steps different from doing w.r.t doing single EP with single R3.
following are the steps i am following
-
Configuration of EP with R/3
To connect to R/3 with EP The following information is needed from the Customer:
R/3 System Information
1.R3-SID 2. Target Client
Portal System Information
1 . Portal URL
There are 2 main steps to configure the EP with R/3 System.
1.Apply Portal Certificate to R3
2.Create System Connection(R3 System Configuration) at Portal Level.
Step1:Apply Portal Certificate to R3
 Insert or adapt profile parameters in the instance profile of the R3 instance. For this you can go Transaction RZ10.or can be done at file system level also
login/accept_sso2_ticket = 1
login/create_sso2_ticket = 2
 Download verify.der file from portal System and upload to R/3 system.
1.Download the Verify.der file from portal : Logon to the portal.
Then goto System Administration  System Configuration  KeyStore
Administration.Then Click on the Download Verify.der button to download the
verify.der file.
Note:make sure that you had logged in to portal with Portal Administrator user belongs to Administrators Group. Or login to portal with Administrator User.
 2. Upload verify.der file to R3 System : logon to R3 with Target client.Then goto
Transaction Called strustsso2.
Import the certificate file:Certificateimport certificate button and specify the path to downloaded verify.der file.As a result the certificate data will be in SAPGUI.
Add the certificate to the list: Add to Certificate List button.As a result in the System PSE gui area the certificate lists contains your certificate.
Add Certificate to the AccessControlList(ACL):Add to ACL button and enter the values for WPS System.ie. WPS=E00 WPS Client = 000.
Save the Configuration.
At the Portal Level you need to enter WPS , Client values. To do that
,logon to portal ,then goto System AdministrationSystem Configuration  UM Configuration  Direct Editing Tab.
Try to add the entrys login.ticket_issuer=WP3 and
login.ticket_client=000 .Then save.
Note:Some of the NW04 based portals,these WPS,Client values cant be saved after clicking Save Button.In that Senario ,you need to upload the
com.sap.security.core.ume.service.sda file through SDM tool of J2EE.
2.Create System Connection(R3 System Configuration) at Portal Level
1 Logon to portal
2. Goto System Administration  System Configuration  System Landscape .
On the Right hand side Portal Content folder is displayed. Open it and check if a subfolder Systems exists.if not,create it to collect all system objects in one folder.Alternatively ,the customer name a target folder where the system object to be created.
3. Select the Systems folder with mouse and click on right button.Select in the open window  New From Portal Achive  System.

Hi Prasad,
As long as the portals all have a different SID, then you can connect as many portals as you want to an SAP system.
