Problem with git push

Hello I have some commits that i need to push. I have commit access to the websites. I am in the gitfedora-web group I am constantly getting the following error Permission denied (publickey). So i dont know what is the issue here. I can ssh to my fedorapeople space with this key i also did configure my git url.correctly to reflect the following origin ssh://git.fedorahosted.org/git/fedora-web.git (fetch) origin ssh://git.fedorahosted.org/git/fedora-web.git (push) also i want to show that my local machine username is tajidin but on FAS its tajidinabd so is that the issue with the key error? thanks Tajidin
