Hello and greetings to everyone in the list,
I have bumped into a weird problem using libcurl 7.19.6 (compiled from source with --disable-ldap as only modifier to configure) on Ubuntu 8.04.
The use case is the following. My Ubuntu has the http proxy well configured (firefox can surf with proxy settings set to use that of the system). According to the 407 response headers, the proxy supports NTLM, Kerberos and Negotiate authorization but doesn't mention Basic. I have a small GUI application that uses libcurl to retrieve a page from another site. (Linked statically if this counts.) When the app sees that the request has failed with a 407, it resubmits the request after having set the CURLOPT_PROXY, CURLOPT_PROXYUSERPWD and CURLOPT_PROXYAUTH variables.
Now comes the interesting part. If I execute the app as a regular user, it authenticates flawlessly with NTLM. If I run it with sudo from a terminal window, same result. However, if I launch it with gksudo, while resending the request, libcurl tries to authenticate using Basic authentication!
I suspect that it may be related to the environment variables since execution with gksudo -k (-k keeps the env) also results in correct behaviour. I tried setenv'ing http_proxy explicitly from the code before doing anything but it didn't make any difference. I also checked the values of all_proxy and no_proxy but they were unset in either case, so were the respective uppercase variables.
Can anybody else reproduce this? Is there another environment variable that I haven't considered?
