Since we're able to configure SSO on vCenter we client, so where vCenter server store the SSO configuration information. I deployed a vCenter Server which use an external SqlServer database. but didn't find a table which seems like to store SSO configuration. but I believe there's a place have vCenter SSO configuration. do you have any idea?
With release of vCenter Server SSO 5.5, you don't need a SQL database to host SSO data like you need in version 5.1, so depending of version you're running, there is no more SQL database.
See the following FAQ: VMware vCenter Single Sign-On Server 5.5 FAQs (2057799) | VMware KB
Do I need a database to successfully install/runSSO 5.5?
No, you do not need a database with SSO 5.5.
What happens to the database that I have with SSO 5.1?
After upgrading to SSO 5.5, the old SSO database is no longer needed. However, the database is not removed from your database server during the upgrade. You must manually remove the database and all users associated with it.
If you want backup your SSO 5.5 configuration, see the following KB article: Backing up and restoring the VMware vCenter Single Sign-On 5.5 configuration (2057353) | VMware KB
