Authentication and Accounting Methods
Advanced RADIUS supports authentication and accounting from livingston formatted text files and databases as well. Supported database connections are ODBC, Oracle and MySQL. Increased security by using encrypted password in database or user's text profiles. Supported encryptions are MD3, MD5, and TEXT (no encryption). Password authentication from local system shadow file is also supported. You can use Password-Authentication Protocol (PAP) or Challenge Handshake Authentication Protocol (CHAP) for user-password authentication type. Time-based authentication and authorization of user is also supported. Fully configurable to use your own choice check-reply attributes for authentication-authorization and custom-attribute selection for accounting.

Flexible Session Handling
You can configure advanced radius to keep online user's session or active sessions. An active session record may be kept in database or in advanced radius internal structure. Advanced RADIUS will use these active session records to control simultaneous multi-sessions and for tracking online user's status. Session records are kept temporary by default, i.e., a session record of a user will be deleted from this section when user disconnects or stops using your service. you can configure advanced radius to store these records in a permanent storage (database / accounting log file) as well.

Realm based authentication and accounting
Realm based authentication and accounting are supported. A realm is selected by advanced radius from user-name@realm-name. This 'realm-name' is used to handle authentication and accounting request from this 'user-name' if realm in defined in radius configurations otherwise a default authentication/accounting handler will be used to process the request.

Best multi-vendor and multiple-radius-client support
Advanced RADIUS may be deployed in a big network using multiple-vendors equipment working as radius-clients. You can use totally different handling of authentication, authorization and accounting (AAA) for each of your NAS equipments at a a same time with same server configurations. Such a distributed handling of NAS equipments (radius clients) with a centralized server provides great deal of localized management and stability.

Configurable multi-session concurrency control
You can allow/restrict multiple logins with same user information. You can configure advanced radius to specify a default maximum multi-session and/or user-specific multi-session attribute. You need to configure advanced radius to specify set of attributes, making a unique user-login. By default, user's login name is the only attribute identifying multiple sessions of same user.

CLI and MAC address based authentication support
You can configure advanced radius to authenticate user on his/her calling number and/or MAC address of user equipment usually used for wireless authentication.

ANI, PIN and account based authentication support
VoIP gateways from different vendors have some different authentication schemes. For example, Cisco AS5300 has two authentication policies for VoIP, i.e., pin system and pin less system. Similarly Quintum gateways support ANI authentication, PIN based authentication, Account based authentication and mix of PIN and Account based authentication.
You can configure advanced radius to work for any authentication schemes like above for user's authentication. See your gateways documentation for more information about such policies.

Redundant/Backup CDR recording support
ARS can be configured to record Call Detil Records (CDR) / Accounting information in multiple databases/text-files in redundant or backup fashion. In case of redundancy, ARS will write records in all the configured accounting handlers. In case of Back-up, it will write CDR information in the first accounting handler only, but if it fails (Due to database crashing, Input/Output errors or lost connection to database) then subsequent accounting handler will record the CDR.

Highly configurable to be integrated with different billing softwares
Different ISP billing sofwares have different methods of storing user information in database. Few billing softwares use one record per table to store user information for authentication by radius, while others use multiple records in a table in attribute-value pair format. Advanced Radius can easily be configured with such kind of billing softwares. ARS has numerous installations with Advanced ISP Billing System for Dialup/DSL/PPPoE services and Advanced VOIP Billing System for VoIP services.

Simultaneous Multi-Vendor gateway Support
Advanced Radius may be deployed in a network environment where VoIP gateways or access servers from different vendors are working on centralized authentication using radius protocol. Advanced Radius may easily be configured to fully serve all multi-vendor gateways with VSA support.

Configurable Logging
Advanced Radius supports multi-level logging for radius server packet tracing. Low-level logging is very helpful in identifying configuration errors, when radius is not handling requests properly. Following are the log levels in descending order:

OFF	No Debugging
SEVERE	Only errors
WARNING	Errors + warnings
INFO	Information about Packets coming and going
DEBUG	Debugging of RADIUS processing. Good for tracing errors
ALL	Intensive debugging

Log output can be generated on console and/or text file. A low log level has great impact on performance, so it should only be used for testing purposes.

RADIUS Proxy & Roaming
Proxy and roaming service is also provided now. You can use Advanced Radius as a forwarding proxy server to one or more radius servers for load balancing and roaming support. Addition of this feature makes it a good choice for your large distributed network.

GUI for Configurations
Configuration of advanced radius made easier and quicker by addition of a user friendly "Radius Configuration Interface". [screenshot].
