Advanced Server Extension Tutorial (Lesson 2)

This tutorial is based partially on the Lesson 1, but extends it in much more ways. It's shown how to use new interfaces IServer, IServer2, ICSVAccounting and ILivingstonAccounting; now a user can be authenticated with MS Access database, MS SQL Server, any ODBC data source, with Windows NT domain or Windows 2000 Active Directory. Accounting data can be recorded in CSV, Livingston-like files or in a database. Both RADIUS and TACACS+ protocols are supported, providing almost equal capabilities except for Livingston accounting logging.

All settings are stored in ini-file.

The source code for the server extension is located in /SDK/AdvancedExt subdirectory of ClearBox Server installation directory.
