Configuration Profiles - Proxy Server Settings

We have used the iPhone Configuration Utility to create a custom profile for our organisation as our Wireless network runs WPA2 Enterprise using EAP TTLS with PAP authentication which doesn't work out of the box as CHAP is the default.

We have successfully deployed this via a web server to a iPod Touch device however we didn't see any means to include our needed proxy server settings.

From the Enterprise Deployment Guide in Appendix 2 there is a mention of Proxy server settings which you appear to have to manually edit into the configuration profile.

However its not 100% clear where they need to go exactly.

At the moment I have them situated within the following tags

<dict>
<key>EAPClientConfiguration</key>
<dict>
...
</dict>
...
</dict>

I believe the section that needs adding are going to be of the form of

1. Manual proxy settings
<key>PropNetProxiesHTTPEnable</key>
<integer>1</integer>
<key>PropNetProxiesHTTPProxy</key>
<string>someproxy.mycompany.com</string>
<key>PropNetProxiesHTTPPort</key>
<integer>8080</integer>

2. Automatic proxy settings
<key>PropNetProxiesProxyAutoConfigEnable</key>
<integer>1</integer>
<key>PropNetProxiesProxyAutoConfigURLString</key>
<string> http://auto.mycompany.com/wpad.dat</string>

Anyone successfully done this as yet?
