Compare your two perl modules. The FreeRADIUS configuration might be identical, but the *CONTENTS* of the /product/freeradius-server-2.1.12_0/etc/raddb//modules/perl files are different between the two servers. On the one, the default example.pl is listed as the perl module. On the other, the module to load has been specified as perl_Originale. Read the debug output carefully when you look at the log, and you would notice the difference. It’s subtle, but it’s there.

Below my radiusd.conf (same file for each servers) and startup of freeradius in debug mode on server A and on server B and you see the difference in loading modules order. Debug log info: radius_debug_server_A.log --> be careful to line number 46 (load perl module) and 62 (load perl_Originale module) radius_debug_server_B.log --> be careful to line number 45 (load perl_Originale module) and 58 (load perl module) [snipped for brevity] -- This e-mail and any attachments may contain confidential, copyright and or privileged material, and are for the use of the intended addressee only.
