Hi David, You can try the below steps: 1. Assume there is a user "bob" and he is member of "Admin Users" group. Execute the following command in terminal: # echo "bob Admin%20Users" | /usr/lib64/squid/wbinfo_group.pl And if you get "OK" as result that means you can go ahead. 2. Take a copy of "/usr/lib64/squid/wbinfo_group.pl" file and open the original file in a editor (vi or nano). Search for "Main loop" section and edit the for loop as follows: foreach $group (@groups) { $group =~ s/%([0-9a-fA-F][0-9a-fA-F])/pack("c",hex($1))/eg; # Add this line $group =~ s/%20/ /; $ans = &check($user, $group); last if $ans eq "OK"; } You have to add one line, which is shown above under the commented section. 3. In you squid configuration replace the space in group name with "%20" to make it look as Admin%20Users. 4. Restart the squid. Try these steps and let us know the result.
