TFS GIT clone failed after upgrade to 2017 : Git Commands Return Fatal: Authentication Failed

Facing "Fatal: Authentication Failed" error while cloning a tfs git repository even if you are provided with enough permissions ? 

Which version of TFS you are using ? Is it 2017 ? 

You need git version 2.9 or later to work with TFS Git for TFS version 2017+ . 

Check your git version with command git --version and upgrade if you have git 2.9 or older.

You are Done . Happy Cloning !!!
