Single Sign-on (SSO) works with any identity provider that allows you to create SSO apps with SAML. SSO is only used to authenticate users. Account permissions are still handled using the Add/Edit users pages in the administrator section of OnDataSuite. When you are ready to set up SSO, go to Administrator >> Site Settings >> Authentication Settings, switch the authentication method to SAML SSO, Import the metadata from your identity provider, and save your settings.
