Gitlab: no user or key was provided

Question

I tried to push the master branch from a client to a server which installed the gitlab. However, I got the following error info:

[root@warehouse git-sample]# git push origin master
[email protected]'s password: 
Counting objects: 3, done.
Writing objects: 100% (3/3), 224 bytes | 0 bytes/s, done.
Total 3 (delta 0), reused 0 (delta 0)
remote: GitLab: No user or key was provided.
To [email protected]:ite-pon/git-sample.git
 ! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to '[email protected]:ite-pon/git-sample.git'

It looks like the gitlab setup a pre-receive hook into the project, but blocked the push operation.

Does anybody has any idea to deal with this issue? Thx~ :)

Below are the detail configuration and information both for server and client:

Server: GitLab & Git & Repository Info

[root@warehouse git-sample.git]# pwd
/opt/gitlab/apps/gitlab/repositories/ite-pon/git-sample.git

1. Gitlab record the client's ssh pub key (no enough reputation to send img :()

2. Setup Administrator (client user) as Master for this project, and as Owner for the domain.

It seems that you reached the bug that just documented on https://gitlab.com/gitlab-org/gitlab-ce/issues/2156 -- the workaround being to remove the key from the authorized_keys files on the server.
