Hey everyone, I'm interested to get FreeRADIUS working with a sqlite backend. My searches around the internet show there is support for sqlite in both 2.x and 3.x versions of FreeRADIUS. I am using 2.1.12 as packaged in CentOS 6. To start, can someone direct me to some documentation online which provides direction to getting this working? I must be looking in the wrong places, because I don't see much documentation for FreeRADIUS when using a sqlite datastore. The first issue I encountered was that there is no schema packaged for FreeRADIUS on CentOS. I worked around this issue by using the schema provided for PostgreSQL. Aside from the commands required to get the DB created, I was only required to remove one or two lines from the PostgreSQL schema: CREATE INDEX radacct_active_user_idx ON radacct (UserName, NASIPAddress, AcctSessionId) WHERE AcctStopTime IS NULL; CREATE INDEX radacct_start_user_idx ON radacct (AcctStartTime, UserName); At some point, I will revisit why these lines threw an error in sqlite, but accounting is a secondary concern right now. The primary concern is authentication, which is failing for pptpd/VPN users. I did manage to get authentication working for Squid users. I only have one record inserted into the radcheck table: [root@host ~]# sqlite3 /tmp/radius SQLite version 3.6.20 Enter ".help" for instructions Enter SQL statements terminated with a ";" sqlite> select * from radcheck; |radtestguy|Cleartext-Password|:=|radtestpw Auth, for Squid, is working beautifully here. Auth for VPN is not working, and I'm not sure why. Here's the full output of radiusd -X: [root@host ~]# radiusd -X FreeRADIUS Version 2.1.12, for host i386-redhat-linux-gnu, built on Oct 3 2012 at 01:20:08 Copyright (C) 1999-2009 The FreeRADIUS server project and contributors.

The answer involve specifying details to connect radius to the file by path, but I'm a bit lost here. I've tried turning on debug logging in rsyslog, but it doesn't provide much more in /var/log/messages than the following: Jan 27 22:37:17 host pppd[17041]: No CHAP secret found for authenticating radtestguy Jan 27 22:37:17 host pppd[17041]: Peer radtestguy failed CHAP authentication Jan 27 22:37:17 host pppd[17041]: sent [CHAP Failure id=0xae ""] Jan 27 22:37:17 host pppd[17041]: sent [LCP TermReq id=0x2 "Authentication failed"] Jan 27 22:37:17 host pppd[17041]: rcvd [LCP TermReq id=0x2 "Failed to authenticate ourselves to peer"] What other configs or sections of configs can I provide that would be helpful?
