Hi everyone, I'm using squid 2.6 with samba authentication. My problem is the following. When I use a blank login and an existing (or existed) login as password on browsers, access is granted although it should not. For example, i had a user "utilisateur" (samba and system accounts) which worked (it can go on internet) I deleted both system and samba account. When i use no login and "utilisateur" for password (on firefox for example), it still works ! Or if i use toto (which is supposed to be a valid samba account) as password, it works too. Here is part of my squid.conf. I'm quite sure it's not a smb_auth program bug because it works in command line (give an error when only got a password) and i modified the sh script used by it to know when it is called by squid process (it is not when no login is given). *** squid.conf *** auth_param basic program /usr/lib/squid/smb_auth -U 127.0.0.1 -W MYDOMAIN auth_param basic realm "Entrez votre login et votre mot de passe" acl Users proxy_auth REQUIRED acl e2c src a.b.c.d/255.255.254.0 acl austrasie src a.b.c.d/255.255.254.0 acl laxou src a.b.c.d/255.255.254.0 acl longlaville src a.b.c.d/255.255.254.0 acl luneville src a.b.c.d/255.255.254.0 acl nancy src a.b.c.d/255.255.254.0 acl all src 0.0.0.0/0.0.0.0 acl working_hours time MTWHF 08:00-20:00 acl localhost src 127.0.0.1/255.255.255.255 acl to_localhost dst 127.0.0.0/8 acl Safe_ports port 80 acl Safe_ports port 443 acl Safe_ports port 21 acl Safe_ports port 20 acl Safe_ports port 1025-65535 http_access allow manager localhost http_access allow purge localhost http_access allow localhost http_access deny !working_hours http_access deny !Safe_ports http_access deny CONNECT !Safe_ports http_access deny manager http_access deny purge http_access allow Users http_access allow nancy Users http_access allow austrasie Users http_access allow laxou Users http_access allow longlaville Users http_access allow luneville Users http_access deny all http_reply_access allow all icp_access allow all *** end squid.conf *** My aim is to allow only 'real' authenticated user from my different subnets, but i don't find out what my mistake is.
