Thanks for your reply, Amos. But how to exclude SSPI helper from compilation? I've tried running "configure" script with --enable-auth-negotiate="kerberos wrapper", and also with --enable-auth-negotiate="none", but in both cases during "make" phase an attempt to compile SSPI helper is made, and the process fails.

Also, I know about Diladele precompiled distributive, and tried it at first, but it misses ext_ad_group_acl helper which I would like to use, so I tried to compile from source. Squid version available as Cygwin package also misses it.
