Hello, I got a problem with ntlm_auth version 3.0.21b - I'd like to use it to authenticate successfully the members of a specified groups only by using the --require-membership-of option. I've been created a group in windows 2000 ADS and let one user be member of it. When I try to use specify the group by its name: ntlm_auth --helper-protocol=squid-2.5-basic --domain DOMAIN2 --require-membership-of='DOMAIN2\groupname' user password [2007/04/25 13:03:50, 0] utils/ntlm_auth.c:get_require_membership_sid(230) Could not parse DOMAIN2\groupname into seperate domain/name parts! ERR If I specify the group with the SID: ntlm_auth --helper-protocol=squid-2.5-basic --domain DOMAIN2 --require-membership-of='S-2-5-21-1174442222-111222401481-452224464-9714' user password ERR It's all what I see. I specified debug and log options but it wasn't more verbose. Could you give me some ideas what should I modify/check to make it work, please? Thanks in advance for responses Best Regards -- Peter
