OS X Server + GIT integration with SSH Fails with

I have GIT server hosted on separate Linux server. I have SSH RSA keys without password.

I am able to connect to GIT Server with Xcode and all operations are working properly in Source Control through Xcode 5.0.2.

I have OS X Server install in my local machine. Following is my OS X Server setup configuration:

Added the Remote Repository as : ssh://myuser@XXXXXXX.XXXX.com:22/iphone_project
I had make sure that my public is correct in OS X Server for SSH. I had copy paste SSH pub key from /.ssh/id_rsa.pub to OS X Server.

Cloning into 'ssh_XXXX_XXXX_XXX_com_22_mtp_iphone'...

SSH Known Hosts file path is located at /Library/Server/Xcode/Config/ssh_known_hosts
SSH strict host checking is disabled (you can enable this by editing the SSHStrictHostKeyChecking key in /Library/Server/Xcode/Config/xcsbuildd.plist
Untrusted HTTPS certificates is disabled (you can enable this by editing the TrustSelfSignedSSLCertificates key in /Library/Server/Xcode/Config/xcsbuildd.plist

My Question is: Why my authentication is still failing after all configuration setup?

Are there any missing point in set up of GIT or OS X SERVER?

Make sure of the exact account which make the ssh command:

Its $HOME/.ssh must have id_rsa.pub, and id_rsa (public and private key).

Make sure the permission of the .ssh folder and its files is correct, as described in "Git SSH authentication" .
With EGit, those folder are referenced and declared in "Eclipse SSH Configuration":
