hi list, i have two proxies on the same network/domain (one is a clone of another) their names are proxy1 and proxy2. I wanted to update one proxy from version 2.5-STABLE10 to STABLE 12. After this update the network authentication via ntlm_auth doesn't work anymore. so i tried to create a domain account for proxy2 again. But after this proxy1 stopped to authenticate! I was confused that my change had an influence to proxy1 ??? Please can anybody tell me what went wrong? 'cause after creating old proxy1 domain account again, this correlations went away. btw: what is the perfect setting for ntlm authentication for about 300 people? my config script: auth_param ntlm program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-ntlmssp /etc/samba/smb.conf auth_param ntlm children 20 auth_param basic program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-basic auth_param basic children 20 auth_param basic realm Squid proxy-caching web server auth_param basic credentialsttl 10 minutes authenticate_ttl 2 minutes authenticate_ip_ttl 20 seconds proxy and domain controller are connected via gigabit. thanks in advance! cheers, andrew
