A method of provisioning organization users in a multi-tenant database system includes receiving a request via a single sign-on protocol from an organization user to create a new multi-tenant database user account for access to the multi-tenant database system. The method retrieves rules that specify how to derive user permissions for access to the multi-tenant database system from stored user attributes of the organization user. The method continues with applying the rules to the stored user attributes to determine permissions for the users to access particular objects in the multi-tenant database system, and creating the new user account with the determined user permissions for access to the multi-tenant database system.
