| Doc Text: |
As a solution to a security issue, GSSAPI credential delegation was disabled, which broke the functionality of the applications that were relying on delegation, which was incorrectly enabled by libcurl. To fix this issue, the CURLOPT_GSSAPI_DELEGATION libcurl option has been introduced in order to enable delegation explicitly when applications need it. All applications using GSSAPI credential delegation can now use this new libcurl option to be able to run properly.

I have proposed a solution upstream: http://thread.gmane.org/gmane.comp.web.curl.general/12226/focus=32265 Whoever is going to commit the fix, please just make sure we use the same option name/constant as upstream. Otherwise we would have incompatible API/ABI. Thanks in advance! I sent improved patch to upstream: http://permalink.gmane.org/gmane.comp.web.curl.library/32355 and I'm currently waiting for response. Upstream requests to take RFC 5896 into consideration: http://tools.ietf.org/html/rfc5896 I have proposed an incremental patch addressing this request: http://thread.gmane.org/gmane.comp.web.curl.library/32355/focus=32374 A new version of the patch reflecting Julien Chaffraix's review comments: http://thread.gmane.org/gmane.comp.web.curl.library/32355/focus=32419 upstream commit: https://github.com/bagder/curl/compare/7688a99bef...a7864c41db Created attachment 516492 [details]
