Fixed In Version: git-1.7.1-8.el6
Doc Type: Bug Fix
Doc Text:
*Git* can now be used with HTTP or HTTPS and SSO Since *libcurl* version 7.19.7-30, a new paramater for delegating Kerberos tickets is required because of CVE-2011-2192. Previously, *Git* did not provide a way to set such a parameter. As a consequence, using *Git* with HTTP or HTTPS and Single Sign-On (SSO) was impossible. With this update, *Git* provides a new `http.delegation` configuration variable, which corresponds to the cURL `--delegation` parameter. Users need to set this parameter when delegation of Kerberos tickets is required.

Comment 2 Kamil Dudka 2016-08-22 15:07:53 UTC 
libcurl provides the CURLOPT_GSSAPI_DELEGATION option to configure credential delegation at the application level:

https://curl.haxx.se/libcurl/c/CURLOPT_GSSAPI_DELEGATION.html

git does not seem to use it currently.  The solution for this bug needs to be discussed with git's upstream first to make sure that we stay compatible with future releases of git.
