Hello! I sucesfully installed a free radius server with ntlm_auth, but have one problem. I have user names in Windows 2003 domain with whitespaces like 'user 1' 'user 2' (i know this is a bit lame, but they was created about years ago and be wery hard to change), these username with whitespaces ntlm_auth string won't authorize. Usernames without whitespaces authorize succesfully. When run ntlm_auth manal and write usernames like 'user 1' than work. And i want put a NT group requirment too like a 'Domain Users' ntlm_auth string is: ntlm_auth = "/usr/bin/ntlm_auth --request-nt-key --domain=%{mschap:NT-Domain} --username=%{mschap:User-Name} --challenge=%{mschap:Challenge:-00} --nt-response=%{mschap:NT-Response:-00}" How can I fix this ? Thanks! P.S. Sorry my englisg isnt perfect :) Andris
