Hi Adrian, Well I ran polygraph with polymix 4 based in cacheboy statistics and added ntlm auth, I look squidclient mgr:ntlmauthenticator and the process are busy after minutes and the polygraph die when all 200 process are busy. When one process of auth is busy, don't open nothing! I tested open any page in firefox in this situation. My samba configuration is simple, bellow the conf. [global] workgroup = MARCOS netbios name = PROXY-TEST realm = AD.MARCOS server string = Marcos server test security = ADS encrypt passwords = Yes password server = TEST.AD.MARCOS log file = /var/log/samba/%m.log log level = 3 max log size = 0 socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192 preferred master = False local master = No domain master = False dns proxy = No wins server = TEST.AD.MARCOS winbind separator = + winbind enum users = Yes winbind enum groups = Yes winbind use default domain = Yes idmap uid = 10000-20000 idmap gid = 10000-20000 client schannel = no Thanks.
