Any thoughts and/or help will be greatly appreciated.Īccording to the man page for bootpd it should in many cases auto detect the format of the data in a DHCP Option code and then automatically process it to the right format, e.g.

I contacted Apple enterprise support and the tier 2 tech said that I can either figure it out on my own or it will cost $700 to escalate it to engineering b/c he did not know how to edit that file either.
I tried to add this into the plist file but it did not work: I found an old article that looks something like this: We have a pac file hosted on a 3rd party server that's all ready to go, so presumably all I need the DHCP to push out is the URL to the file but I can't find how to write the code into the file, where to add the code into the file, and what the exact syntax should be. I don't know the code and/or syntax to add this to the plist file. I see from your posts that we need to edit the ist and add an option for 252. I'm trying to push out a proxy pac file via DHCP from an Apple server to Apple devices (iOS and OS X) and all I seem to come across is your stuff! Well done getting apple to add support for this on OS X Server. This is a per-user setting so another user even on the same Mac would get asked for their own authentication details. If your using Firefox it stores it itself. It is either possible to not use any authentication requirement at all, or if you do what will happen is that the first time the user gets asked a dialog is presented asking for the username/password and this is then saved in the users login keychain - if your using Safari and/or other Apple applications. Note: The authentication settings are not provided via WPAD. Apple call this 'Auto Proxy Discovery' in their Proxies tab in Network Settings.įor more details about WPAD see this article - įor more details about the actual PAC configuration file see - the proxy.pac and wpad.dat files are really the exact same thing. The advantage of this approach is that if you take a laptop out of the office it does not need reconfiguring to not use your LAN proxy server any more.Īs it happens I got Apple to add support not only for defining DHCP option codes in their own DHCP server and hence being able to define option 252 needed for this purpose, but I also separately got Apple to add support in OS X to act as a client for WPAD to 'learn' what proxy server to use. The above is for a network standard called WPAD - Web Proxy Auto Discovery which was originally devised by Microsoft and originally incorporated in Internet Explorer. Note: the proxy.pac file not only contains the address of your proxy server but also rules about which sites can bypass the proxy server, and sites that can go via the proxy server but bypass authentication.
wpad.dat file available via an internal web-server and in view of 2. Optionally define a DNS record for your internal network, this could be an A record but more typically would be a CNAME and would be for.Set up a DHCP option code 252 to define the address of a web server that 'serves' a proxy.pac aka.It does not answer your specific question but I would say in general that the best way to push proxy settings is as follows.
