Thanks Eliezer for reply. Its is working now for be perfectly with below command with -d option gives helpful debug info to troubleshoot.
external_acl_type AD_Group %LOGIN /usr/lib64/squid/squid_ldap_group -P -R -b "DC=ABCD,DC=GOV,DC=IN" -D svcproxy -w 123456789 -f "(&(objectclass=person)(userPrincipalName=%v)(memberof=cn=%a,ou=InternetAccess,ou=Groups,dc=ABCD,dc=GOV,dc=IN))" -h abcd.gov.in -s sub -v 3 -d Currently I have configure squid with AD kerberos auth. also url access restricted based on AD group membership. Now I observed, is that when I add any user to one of the AD group which allowed in squid. it is not accepting the changes until I restart the squid service. Is this the way squid behave or do I need to follow different procedure. So as user added to AD group it will recognised by squid on the fly without restarting squid service.
