Hello, I'm in the process of updating old 1.x freeradius servers to 2.1.10. We have scripts which fire to verify some local verifications and return some attributes which get passed along with the response to the NAS. The old method used Exec-Program-Wait in the users file; however, per recommendation in docs and list I'm converting things over to use the newer rlm_exec method. The new method works great for local authentication; however, I'm getting stumped on requests which are proxied to another radius server which accepts the request. Process of events: 1. Auth request is proxied to 3rd party server, which returns an Access-Accept rad_recv: Access-Accept packet from host 10.0.0.243 port 1645, id=184, length=37 Framed-Protocol = PPP Framed-Compression = Van-Jacobson-TCP-IP Proxy-State = 0x313238 2. As configured in post-proxy, visp_proxyauth is run. For the sake of simplicity visp_proxyauth executes a script which simply responds with exit 1 to mimic a failed local verification. # Executing section post-proxy from file /usr/local/etc/raddb/sites-enabled/default +- entering group post-proxy {...} Exec-Program output: Exec-Program: returned: 1 ++[visp_proxyauth] returns reject Found Auth-Type = Accept Auth-Type = Accept, accepting the user Problem, even though visp_proxyauth returns reject with exit 1, I believe the earlier Auth-Type = Accept from the response of the 3rd party radius server the request was proxied to is being used to accept the login. This differs from how 1.x acted in that if exec-program-wait returned exit 1 it would fail the request. My new install of 2.1.10 accepts the request which is not the desired behavior. I'm definitely open to modifying my config or exit codes to accommodate any differences introduced in 2.x. I've seemingly tried too many different configuration options and different tactics to try to make this work but seem to be stumped and looking for some outside perspective. My goal would be to ultimately reject the request if visp_proxyauth exits with return value 1 (user reject). Any assistance is greatly appreciated. - N Complete debug output follows: FreeRADIUS Version 2.1.10, for host x86_64-unknown-linux-gnu, built on Jun 15 2011 at 18:03:23 Copyright (C) 1999-2009 The FreeRADIUS server project and contributors.
