Use Git LFS with TFS 2015 Update 2 OnPremise

Question

TFS 2015 Update 2 brings Git LFS support, but when I tried to use it with the Brian Keller VS2015ALM virtual machine (upgraded to Update 2), I got this exception :

git-lfs/1.2.0 (GitHub; windows amd64; go 1.6.1; git 386c5d8)
git version 2.8.1.windows.1

$ git-lfs.exe smudge -- Image1.jpg

This appends when I tried to push with git.exe and works after a first push with VS2015U2. But now I got this error when I try to re-clone my repo (failed on checkout) with git.exe or VS2015U2. By the way, VS completly crash in this case. I tried the same operations with VSTS, and no error occured (with git.exe, GitExtensions or VS2015U2). So it seems to be a problem with how credentials are provided but how to fix it ?

Repo steps :

1. Create a repo on TFS web portal
2. Clone it with VS or git
3. Execute "git lfs install"
4. Execute "git lfs filter track "*.jpg""
5. Add an image to workspace
6. Commit
7. Execute "git push origin master" => failed with git.exe
8. Execute "git push origin master" => works with VS
9. Add a second image and commit
10. The push now works with git.exe
11. Delete local repository
12. Clone repo => failed on checkout with git.exe or VS

I tried with "clone -n" to avoid immediate checkout, then I execute "git lfs install" and "git checkout master", same exception occured : Your user name must be of the form DOMAIN\user. It is currently brian%!(EXTRA st ring=string)

Answer 1

Git Credential Manager for Windows helps me to get it work.

Just use GCMW and at the first credential prompt (credentials are stored in the Windows Credential Manager) :

• username: "vsalm\brian"
• password: "P2ssw0rd"

And it works.

• Without GCMW it does not work.
• It works with the GCMW provided by the Git 2.8 installation, the manual installation of 1.2.2 and 1.3 (by adding "[credential] helper = manager" in gitconfig)

Note: Clone with VS2015U2 doesn't work, a fix is plan in U3. More info: https://connect.microsoft.com/VisualStudio/feedback/details/2657886/cant-use-git-lfs-with-tfs-2015-update-2-onpremise
