Ok thanks again Amos. The plan is then: - external acl helper gets the SRC and connects to REST server running on AD DC with IP <-> user mapping database - replies with OK user=<name> - this name get's delivered to access log and ICAP/eCAP - (optional) we are able to match the user to security group and apply designated filtering policy in our ICAP server. Written above seems to work in the test lab.

Though AFAIK neither of them uses the AD interface (YMMV if the Perl DB module can use AD as an SQL-like database). You might be able to also be use the Basic auth LDAP helper from Squid-3.4+ as an external ACL helper. It will require some fiddling of the LDAP parameters and the ACL input format to make the external ACL input into the Basic-auth lookup.
