Dear Vellingiri,
You need to authenticate the users against a list or make a list of users who
should not be allowed access. Add the following ACLs -
acl <group_name> proxy_auth -i "<path to the file containing list of usernames>"
eg. acl allowed_users proxy_auth -i "/etc/squid/users/allowed_users"
http_access allow <group_name>
eg. http_access allow allowed_users
If you want to deny only one user, you may modify the above rules to exclude
that user.
Hope that helps.
Regards
Gorav
