Users will simply need to provide their CtrlPrint username when logging in after SSO is activated. This is a unique identifier and not the user’s email address.
If they are already logged in to their IDP they will be taken to their start page in CtrlPrint. If not, they will be asked to log in with their IDP credentials before being taken to the start page.
If a user is unable to log in to their IDP they will not be able to log in to CtrlPrint. There is not a way to bypass SSO and log in with a regular password.
