Here, you can allow or restrict your users from receiving or sharing, exporting, and publishing documents within your organization or outside your organization. This gives you the advantage of protecting your organization documents from unnecessary distribution.
If you'd like to make another admin as the super admin, you can do it here. The super admin has full control of the organization account, where he can define and manage the password policy for the organization unlike an admin.
You can configure the SAML URL and the public key. A user from your organization should login with his/her domain say "https:// business.zoho.com". The user will be redirected to the IDP provided for SAML with the SAML request for authentication. The IDP will authenticate and send us the SAML response. If the response is success, a ticket will be generated for him and will be set in the cookie.
