I have been noticed that one of our SharePoint 2010 installation has a problem when trying to click on Secure Store Service in central administration.
The problem is : Try to click on SSS service in Central Administration and you will get an error page.
How to check the exact problem: I checked the event log in my server and i found the following error:
The Secure Store Service application Secure Store Service is not accessible. The full exception text is: The HTTP service located at https://PORTALURL/b04c52908ae5479596745e86b13875d4/SecureStoreService.svc/https is too busy.
To cause of the problem: the SSS service is not provisioned correctly, and to fix it:
Select the secure store service and from the ribbon click on properties. Verify the information that you have and click on OK. this action will provision the required DB and other service application configuration for this service.
This action will take around 5 minutes or depends on the performance of your server.
You don't need to re-install or run the configuration wizard for this fix.
Hope this helps :) Happy SharePointing...
