Hello, I have got Proxy access controlled by NT Groups working with my Windows 2000 Domain... but the problem I am having is that Squid does not recognise changes to the groups until I restart winbindd and squid. Squid 2.5.STABLE13 NTLM with Samba-3.0.21c and Access Controlled with NT Groups (Windows 2000 domain) Here are some excerpts from my configs: squid.conf: auth_param ntlm program /usr/local/samba3/bin/ntlm_auth --helper-protocol=squid-2.5-ntlmssp auth_param ntlm children 30 auth_param ntlm max_challenge_reuses 0 auth_param ntlm max_challenge_lifetime 2 minutes # ntlm_auth from Samba 3 supports NTLM NEGOTIATE packet auth_param ntlm use_ntlm_negotiate on auth_param basic program /usr/local/samba3/bin/ntlm_auth --helper-protocol=squid-2.5-basic auth_param basic children 5 auth_param basic realm Squid proxy-caching web server auth_param basic credentialsttl 2 minutes external_acl_type NTGroup ttl=60 %LOGIN /usr/local/squid/libexec/wbinfo_group.pl acl AccessInternet external NTGroup Proxy_Access_Internet http_access allow AccessInternet http_access deny all smb.conf: workgroup=my_domain_name password server = my_domain_controller security = domain winbind uid = 10000-20000 winbind gid = 10000-20000 winbind use default domain = yes winbind cache time = 2 Any help would be greatly appreciated!
