Thank you very much for your response in answer to my request. Sure, i shall send the debug version soon. i want to understand also, how simultaneous check works. Is there any documentation which i can read to understand the process stage?
The server comes with a file "doc/Simultaneous-Use".
Could you kindly, tell me at which stage of the process simultaneous login check is performed ? such as "post auth" or ?
It's in it's own section, called "session" for historical reasons.
Yesterday i forgot to mention that all related include directives in "radiusd.conf" are opened, such as include "dialup.conf". i also did not mentioned that i do use MySQL DBMS with radius accounting. Yes, accounting is logged in database. FreeRADIUS has been installed on UBUNTU 12.4LTS & Version is Following
None of that matters. 1. Can the user get authenticated at *all*? 2. Have you set 'Simultaneous-Use = 1' for the user? 3. Is the server receiving ANY accounting packets? 4. After the user gets authenticated, does FreeRADIUS receive accounting packets for that user? 5. Is the radutmp / sql module logging those accounting packets? 6. Do the accounting packets have enough information to uniquely identify a session? i.e. no "NAS-Port = 0" for all users 7. Is the nas_type in the "client" configuration set to a known NAS, where the server can double-check logins? 7. When the user logs in a second time, does FreeRADIUS even try Simultaneous-Use checking? The configuration is composed of a set of interlocking pieces. They ALL have to be configured correctly for Simultaneous-Use to work. Some of the problems can be due to the NAS, which misbehaves.
