The SSO database is the SQL Server database that stores the information about the affiliate applications, as well as all the encrypted user credentials to all the affiliate applications. The master secret server is the Enterprise Single Sign-On server that stores the master secret.
Where is SSO data stored?
SSO stores the credentials in the Credential database. Because SSO provides a generic single sign-on solution, middleware applications and custom adapters can take advantage of SSO to securely store and transmit user credentials across the environment.
Does SSO use Active Directory?
If you install only the SSO Agent, the SSO Agent uses Active Directory (AD) Mode for SSO.
