Well, IMHO this definitely shouldn't work without a curl_easy_reset: once the server has sent a 401 without Basic, curl knows the server doesn't accept Basic auth and shouldn't send it. (It's ok for curl to send Basic auth with its first request, before its received a 401, since that will save a roundtrip if the server happens to accept it.)

In theory doing a curl_easy_reset should cause curl to forget all details of the previous responses, so it should go back to sending your Basic auth. But there was a recent bug with this, which should be fixed now.

Aha. The fix was made just AFTER the 7.27.0 release. Try downloading the most recent code from git and compiling that to see if it fixes your problem.
