Hi, I have configured my freeradius server to authenticate users against an external server (LinOTP server) using a perl plugin. The authentication is working correctly. My users' conf file "*/etc/freeradius/users*" contains the following: *DEFAULT Auth-type := perl* The linotp module configuration is as follows: *authorize { preprocess IPASS suffix ntdomain files expiration logintime pap}#here the linotp perl module is called for further processingauthenticate { perl}accounting { detail unix radutmp exec attr_filter.accounting_response}*I need to know how can I provide IP addresses to connecting users using the " *Frame-IP-Address*" attribute while still autheticating against the external server?? Thanks for your help! (Sorry for the last incomplete mail)
