Pidgin support for "Environmental Settings" for proxy configuration

[Bart Teekman]

Hi,

On the network tab I set the Proxy Type to "Use Environmental Settings". Our
proxy requires authentication and for other applications (such as Firefox)
the software is able to connect to the proxy using my signed in windows
credentials, but Pidgin does not do this meaning outbound connections are
rejected.....

A copy of the debug is shown below:

12:55:39) *account:* Connecting to account <account>@gmail.com/Home

Clearly shows all is well until the auth challenge....is there a fix or will
this need to go on the enhancements list? Iknow I can manually specify the
settings, but as I running the app in portable mode between multiple
environments it would be MUCH easier if it just picked up the client
workstation settings and just worked....now I have to manually change the
settings about 4-5 times per day....

Thanks,
B.
