Two remoteauthentication protocols are supported: LDAP and RADIUS.Notice Only people experienced with the AAA architecture andauthentication protocols should make changes on this page.Moving logins to a centralized server can provide enhanced security for anumber of reasons, such as:■ less work is required to manage password-controlled access to all basestations in a network; you no longer need to change the password ineach base station individually.■ previously used passwords may be excluded from re-use.■ access can be denied after a set number of incorrect passwords isentered.■ passwords can be set to expire on a certain date.■ remote access to base stations can be globally enabled and disabled asrequired for technical staff during the commissioning process.Once the centralized server logins are set up, we recommend that only onelocal administrator login is left on the base station for emergency use(e.g. when the connection to the server is lost). The password for thisemergency login should be kept secret.
