 On the other hand, the other authentication methods use the same types of login info (username and password), but authenticate using external auth systems rather than AWX's own database. If some of these methods are enabled, AWX will try authenticating using the enabled methods *before AWX's own authentication method*. The order of precedence is:
-* RADIUS
 * SAML
 
 ## Notes:
-SAML users and RADIUS users are categorized as 'Enterprise' users. The following rules apply to Enterprise users:
-
   * Enterprise users can only be created via the first successful login attempt from remote authentication backend.
   * Enterprise users cannot be created/authenticated if non-enterprise users with the same name has already been created in AWX.
   * AWX passwords of Enterprise users should always be empty and cannot be set by any user if there are enterprise backends enabled.

 Account authentication can be configured in the AWX User Interface and saved to the PostgreSQL database. For instructions, refer to the :ref:`ag_configure_awx` section. 
 
-Account authentication in AWX can be configured to centrally use OAuth2, while enterprise-level account authentication can be configured for :ref:`Azure <ag_auth_azure>`, :ref:`RADIUS <ag_auth_radius>` as a source for authentication information. See :ref:`ag_ent_auth` for more detail.
-
-For websites, such as Microsoft Azure, Google or GitHub, that provide account information, account information is often implemented using the OAuth standard. OAuth is a secure authorization protocol which is commonly used in conjunction with account authentication to grant 3rd party applications a "session token" allowing them to make API calls to providers on the user’s behalf.
-
-The :ref:`RADIUS <ag_auth_radius>` distributed client/server system allows you to secure networks against unauthorized access and can be implemented in network environments requiring high levels of security while maintaining network access for remote users.
