Description: Defines the method of authentication. Either individual users, or the entry can accomodate various methods of authentication. The 'always reject' will prohibit the corresponding user (specific or default) from ever being authenticated. The use of 'always accept' will always authenticate the corresponding user, regardless of which password was used. 'Internal Authentication' performs password validation for a specific user. 'Radius Authentication' attempts to use a configured Radius server to determine whether or not a user is authenticated.
