I have my Ubuntu Server set up so users with the group of sftponly can
connect with sftp, but have a shell of /bin/false, and they
connect to their home directories. This is working fine with three of the user accounts I have. But I added a new user account today the same way that I added the others and it will not successfully
connect.
sftp -vvv user@hostname

I cannot figure out why one user will work and the other wont, I have restart the ssh service after adding the user. I have even removed the user and added them again to be sure I am adding it correctly.
