Hi, I have searched the web and seen the articles on this subject, but still cannot get it to work. At the moment, i have created a file called proxyauth and put it into the NETLOGON share of my AD, with allow the only text inside the file. I have smb running, when i type the following command (/usr/lib/squid/smb_auth -w ADMIN -U 10.0.0.1 -d) with a valid AD username and password it always comes back with ERR, and doesnt return the allow text thats inside the proxyauth file (blank at end of contents line). Therefore i assume its a permissions issue on my AD box. What permissions do i need to change and do i need to only change the permissions to the file or to the NETLOGON folder?. Is there anything else i need to do to get it working? Thanks in advance. Adam
