give permission to application ssh user to create his own ssh key
- create an app on any server
- add ssh user to app
- activate ssh access for app
- log in as ssh user created
- try to do ssh-keygen
The user can't write to ~/.ssh which is a problem.
I can't give a partner en environment with git enabled to push / pull from a remote origin.
Only work around now is to fire up a new server instance or give everyone master credentials.
