enable ssh user login (Debian)

Question

How can I enable ssh for user administrator?
I use this in sshd_config:
AllowUsers administrator
After restart ssh, I tried login, I typed username + pw, but I dont got any answer. Whats wrong?
Maybe this settings are the reasons?

Match group filetransfer
    ChrootDirectory %h
    X11Forwarding no
    AllowTcpForwarding no
    ForceCommand internal-sftp
