Why TFS with GIT is not working from command line?

Question

I want to use the git command line tools with the Microsoft Team Foundation Server Git repositories.

But every time I want to access to remote repos the authentication fails. And of course I am using Active Directory (this is a TFS server). The git repo management works perfectly from Visual Studio. (even push, sync, clone, etc).

Cloning into 'blabla'
fatal: Authentication failed for 'http://server:8080/tfs/BlaCollection/_git/blabla/'

I have intented using this patters and always fail.

• DOMAIN\username
• username@domainforest

Anyone has get connected using command line tools to a TFS with git server? In my company we use tokens to log on Windows, may be the reason?

Answer 1

Windows Credentials -> Generic Credentials

Then add a new item with "git:" in front of the http:// i.e.:

git:http://Example.com

add domain\user as user, and password

Answer 2

I did two things to make it work. Try below.

1. Update your git to the latest version.
2. Open Windows Credential Manager by typing the same in Windows Search and remove the git credentials in the generic credentials as shown below

Answer 3

Finally a collegue hit the solution and I will post it here:

Use the command:

git config --global credential.http://[tfs_server].integrated true

Of course, replace [tfs_server] with your own TFS server host name.

When Credential Manager asks for credentials just leave blanks and press OK. (I this way authentication will be performed using Kerberos).
