Squid and NTLM authentication
 

I am new on this forum .
I try to install a proxy server using squid 2.6.STABLE5 for i386-debian-linux .I have installed samba, kerberos , windbind .

I have configured the squid.conf like this :
auth_param ntlm program

/usr/bin/ntlm_auth--helper-protocol=squid-2.5-basic --require-membership-of=AURUS-SYSTEMES.LOCAL\\accessweb
auth_param basic children 5
auth_param basic credentialsttl 2 hours
acl ntlm proxy_auth REQUIRED
http_access allow ntlm

I have tested the ntlm_auth and it works fine


When I run a browser using with an account not in the accessweb group , the system ask for a username password .

I cannot display any pages . The log files gives :

I get the same thing when I log with an account in the appropriate accesweb group .

Any Idea or clue ?

Thanks in advance
