Hi all,
The following has been tested with versions
- 7.29.0 (x86_64-redhat-linux-gnu)
- 7.61.1 (x86_64-redhat-linux-gnu)
- 7.64.0 (x86_64-w64-mingw32)
I'm trying to use curl with Negotiate like so:
curl -kv -L --negotiate -u : -b ~/cookie.txt -c ~/cookie.txt
http://localhost:8081/negotiate
If the first 401 response contains
WWW-Authenticate: Negotiate
curl will then, as expected, send another request with an Authorization header:
Authorization: Negotiate xxxxxxxxxxxxx
However, if the 401 response contains more than one challenge, like so:
WWW-Authenticate: Negotiate, Basic realm="TM1"
curl will NOT send another request. According to RFC2616 [1], sending multiple
challenges like this is valid.
Is there a way to handle this case, or is this a bug in libcurl? Ultimately,
I'm trying to do such requests using
R which uses libcurl under the hood.
Thank you for taking the time,
Michel Jung
