NOTE NOTE • With authorization method Use PHP code to assign a user role (Advanced) - more complex authorization rules can be implemented to specify which role to assign to an authenticated user. Authorization can use any of the available properties of the user account, as well as taking into account other factors such as the time of day, previous usage, and more. Advanced authorization - Example 1 This example covers the case where a domain contains several organizational units (OUs), and the users in each OU are to be mapped to a specific RADIUS role ID. To determine the appropriate role ID, navigate to RADIUS Services > User Roles and check the ID column for the appropriate role. For example, to implement the following configuration: • OU East should be mapped to RADIUS role ID 4 • OU Central should be mapped to RADIUS role ID 5 • OU West should be mapped to RADIUS role ID 6 Make sure the following configuration is set: 1. First, ensure that the Base DN for the authentication server is set to the root of the domain - for example: DC=amigopod,DC=local - rather than the "users" container. This is necessary as the organizational units are located below the top level of the directory and cannot be searched from the CN=Users container. 2. Select the authorization method Use PHP code to assign a user role (Advanced) and use the following code: if (stripos($user['distinguishedname'],'OU=East')) return 4; if (stripos($user['distinguishedname'],'OU=Central')) return 5; if (stripos($user['distinguishedname'],'OU=West')) return 6; return false; Explanation: During user authorization, the distinguished name of the user (which will contain the user's OU) is checked against the defined rules, and an appropriate role ID is returned. If no match is found, false is returned, which means that authorization fails and the user's Access-Request will be rejected. Advanced authorization - Example 2 This example covers the case where users are assigned group memeberships, and users in a particular group are to be mapped to a specific RADIUS role ID. To determine the appropriate role ID, navigate to RADIUS Services > User Roles and check the ID column for the appropriate role. For example, to implement the following configuration: • Members of the Domain Admins group should be mapped to RADIUS role ID 4 • Members of the Users group should be mapped to RADIUS role ID 5 • All other users should be rejected Make sure the following configuration is set: 12| External Authentication Servers Amigopod |Technical Note
