I installed gitlab on my servers at linode. All services of gitlab are working fantastic. I am able to login, create users, repos etc. But the problem I am facing is when I try to push a repo it prompts a password for the git user as follows:

[email protected]'s password

I have followed the instructions of installing gitlab at: https://github.com/gitlabhq/gitlabhq/blob/master/doc/install/installation.md and have disable the login got the user git using the following line mentioned in the installation guide:

sudo adduser --disabled-login --gecos 'GitLab' git

I am using gitlab version 6. What could be the problem?

The output of: ssh -Tvvv [email protected] is as follows:

I had the same problem but it was because my server only accept ssh login from users of "sshusers".

On /etc/ssh/sshd_config I had the following line : 

AllowGroups sshusers

In order to fix this issue, I added git to sshusers group: 

$ sudo adduser git sshusers

And then it's working.
