Testing Active Directory User Authentication To verify that the domain has been joined successfully, click the Test Authentication command link on the RADIUS > Authentication > Active Directory page. Provide a username and password for a user in the domain to verify that authentication is working. The following options are available in the Authentication drop-down list:  MS-CHAPv2 - Encrypted password - Use this option to encrypt the user's password using the MS- CHAPv2 authentication method and verify it with the server. A successful authentication using this method can only be performed when the Amigopod Visitor Management Appliance has joined the domain.  Plain text password - Use this option to perform a plain-text verification of the user's password. Configuring Active Directory Domain Authentication After joining the domain, an additional step is required in order to perform user authentication. The username and password of a domain user is required to perform an LDAP bind to the Active Directory domain controller, so that LDAP search operations can be performed for other user accounts in the directory. The credentials provided do not need to be those of a domain administrator; a restricted user account may be provided here. Only user lookup operations are performed with this user account. To provide the domain credentials that will be used when authenticating via LDAP, click the Configure Active Directory authentication link on the RADIUS > Active Directory Services page . 90 | RADIUS Services Amigopod 3.7 | Deployment Guide
