Hey Nilesh,
Did you tried to test it in any way outside of squid?
Like in a command line as a self running program?

Subject: [squid-users] URL access based on AD group membership
Team;
Need expert help here,
here is my set up - as of now squid integrated with Windows 2012R2 AD, SSO
with kerberos - working fine.
Now I want to restrict Internet access for user based on their AD group
membership. I tried loads of options from various site but no luck. not sure
what is going wrong.
here is my squid config, and cache.log o/p.
