i want to join this discussion. we are using squid 3.4.2 also with ntlm_auth and winbind. only difference is that we don't use wbinfo_group. we just "need" or "use" the username. we also have the problem, that after a few minutes squid uses 100% cpu and is getting very slow. in the cache-log I can see "increase ntmm-helper" as the max number is used. I also can see in the cache manager menu output (ntlmauthenticator) that all the configured helper are "busy". any idea about the 100% cpu usage? > -----Ursprüngliche Nachricht----- > Von: Alex Crow [mailto:alex@xxxxxxxxxxxxxxx] > Gesendet: Sonntag, 29.
