Hi David, You can try "/usr/lib64/squid/wbinfo_group.pl". For testing purpose run following in terminal: # echo “username windowsgroup” | /usr/lib64/squid/wbinfo_group.pl -d And if it return something as: Sending OK to squid OK Then you can use it in your squid config. If you are using kerberos then you have to do some modification in "/usr/lib64/squid/wbinfo_group.pl" file as this helper is designed for NTLM naming. Just open the file in any text editor and change the "sub check {" section look as follows: sub check { local($user, $group) = @_; my @DATA = split (/\@/, $user); $user = $DATA[0]; ................ Make sure that you take a copy of this file before editing. Hope this will help.
