Hi all, I'm trying to use regular expressions as realm names in the proxy.conf file. There is an example and explanation of writing regular expression as a realm name in the proxy.conf file. However it is not working even if I write down the given example. Radius startup breaks up with the error message: Invalid regex in realm "~*\.example\.com$" My proxy.conf file is look like: .. .. .. realm "~*\\.example\\.com$" { authhost = LOCAL # not strictly necessary accthost = LOCAL # not strictly necessary } realm DEFAULT { .. .. .. and the output is as follows: ~# radiusd -X FreeRADIUS Version 2.1.1, for host i686-pc-linux-gnu, built on Nov 3 2008 at 16:11:36 Copyright (C) 1999-2008 The FreeRADIUS server project and contributors.

Has the update of explanations in proxy.conf file forgotten or my configuration contains any error? Thanks for your help. Best regards, Gokhan Eryol
