squid helpers

Hi All, I am having trouble testing the ntlm_auth helper for squid. When i run: ntlm_auth --helper-protocol= I get a list of helpers and squid-2.5-basic is listed. But when i run ntlm_auth --helper-protocol=squid-2.5-basic mydomain+myuser mypasswd nothing happens i have to press ctrl+c. If i leave the helper out i get OK. What is cache_effective_user?
