Single Sign On In CRM Web UI
As the title of blog I would like to share approach for SSO in CRM Web UI and problem appears after upgrade with solution.
Subject
Personally I prefer to Logon in CRM Web UI to save some precious minutes in my day-to-day work. Here I would like share 'how to' do this in your system.
How To
Please find below steps:
1. After log in SAP GUI, right click on Favorites -> Add Other Objects
2. Select BSP Application
3. Please provide BSP application CRM_UI_START with user id and password in <marked> places
4. Select OK and Favorites would be added, after double click on 'Starts the CRM UI Application Frame' -> it should log on in Web UI without asking for user and password
Problem after upgrade to EHP3
After our system is upgraded to EHP3, suddenly I am not able to log on and it stops with error message 'Logon with URL parameter not possible; logon cookie is missing'
Resolution
After searching for some time, I have found that this error message is triggered due to a flag 'Deactivate Login XSRF Protection' in BSP application CRM_UI_START. It is by default not selected and we need to select this check box and to do that please go to transaction SICF
After selection, please double click on service to go inside. Click on Error Pages tab -> with sub tab Logon Errors -> scroll down to go to System Logon -> click on Configuration
Select the check box 
and press OK and Save
Please try the Favorites menu again and it would log on without error message
