3.41. <AuthBy EMERALD> Previous topic Parent topic Child topic Next topic

<AuthBy EMERALD> provides authentication and accounting using the popular Emerald ISP billing package from IEA website Opens in new window. The combination of Radiator and Emerald provides a very powerful and easy to use ISP billing and user management system. You will be able to add users to Emerald, and have them able to log in immediately. Changing their password takes effect immediately, and all user logins are available as soon as they are completed: no need to import accounting files.
Users of Emerald version 4 should use the <AuthBy EMERALD4>, following the instructions provided by IEA.
This AuthBy method will also work for Platypus when it has its optional RadiusNT compatibility package installed.
Emerald uses Microsoft SQL for its user database, so in order to make Radiator work with Emerald on Unix, you will usually need to install an ODBC driver, plus the Perl DBD-ODBC module. Alternatively, you can use the DBD-Sybase module and the Sybase client libraries. More details on connectivity between Unix and MS-SQL on NT can be found in the Radiator FAQ.
During authentication, Radiator checks the password in the Emerald “masteraccounts” and “subaccounts” tables. It also checks the expiry dates, extensions and time left. It also gathers radius reply attributes from the RadConfigs and RadATConfigs tables. The RadATConfigs table (which contains per-account-type radius reply items) is only consulted if there are no per-user reply items for the user in the RadConfigs table (but you can change this behaviour with AddATDefaults. For more information, see Section 3.41.2. AddATDefaults.
By default, AuthBy EMERALD takes no notice of the LoginLimit from the Emerald database. If you wish to honour it to limit the maximum number of simultaneous logins for a user, add this to your Radiator configuration:
# use the LoginLimit from the emerald database
AuthSelect ,sa.LoginLimit
AuthColumnDef 0,Simultaneous-Use,check
<AuthBy EMERALD> does not use the RADIUS client configuration and secrets entered into the Emerald “Radius Config”. You still need to configure a <Client> clause in Radiator for each NAS you are going to use.
<AuthBy EMERALD> will connect to the Emerald database as the user you specify in the DBUsername parameter. You will probably have to create such a login in your database, and make sure they are a member of the Emerald database group.
During accounting, Radiator logs call details from each Accounting request to the Emerald “Calls” table.
There is an example Radiator configuration file for Emerald in goodies/emerald.cfg. You should use this as the starting point for configuring Radiator to work with Emerald.
<AuthBy EMERALD> understands also the same parameters as <AuthBy SQL>. For more information, see Section 3.37. <AuthBy SQL>.
