Hi, Free Radius 2.1 It is working just fine on Windows XP and Windows Mobile. However Windows CE is asking for a username and domain. On Windows XP and Mobile it is just asking for username and password. Here is the output from radiusd -x -X Wed Oct 22 06:56:19 2008 : Debug: ++[preprocess] returns ok Wed Oct 22 06:56:19 2008 : Debug: modsingle[authorize]: calling chap (rlm_chap) for request 1 Wed Oct 22 06:56:19 2008 : Debug: modsingle[authorize]: returned from chap (rlm_chap) for request 1 Wed Oct 22 06:56:19 2008 : Debug: ++[chap] returns noop Wed Oct 22 06:56:19 2008 : Debug: modsingle[authorize]: calling mschap (rlm_mschap) for request 1 Wed Oct 22 06:56:19 2008 : Debug: modsingle[authorize]: returned from mschap (rlm_mschap) for request 1 Wed Oct 22 06:56:19 2008 : Debug: ++[mschap] returns noop Wed Oct 22 06:56:19 2008 : Debug: modsingle[authorize]: calling suffix (rlm_realm) for request 1 Wed Oct 22 06:56:19 2008 : Debug: rlm_realm: No '@' in User-Name = "barcode\gun1", looking up realm NULL Wed Oct 22 06:56:19 2008 : Debug: rlm_realm: No such realm "NULL" Wed Oct 22 06:56:19 2008 : Debug: modsingle[authorize]: returned from suffix (rlm_realm) for request 1 Any suggestions?
