git cloning and copying files from the repository

Hello All,

This is John. I am new to 'git' and I have a git project repository in project locker, After doing an "git init" in /opt/testgit/ I am tying to clone to git, using the command

$git clone git-username@free2.proectlocker.com:projectName.git

I am getting the following reponse

git-username@free2.projectlocker.com's password

I am entering the right password only(the same I use for logging in the project locker as the 'username' mentioned, but here it dosen't accept tat error and says "permission denied, please try again" and throws following message after 3 times--

permission denied (publickey,gssapi-with-mic,password)
fatal: The remote hung up unexpectedly

Am I missing something, or is there anything else required to copy the repository into the current directory

Thanks
John Carlos
