Hi, I'm running freeradius version 2.1.12. 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 processing authenticate { 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! Hatim
