Respuesta: Problemas con SFTP

Para más información, he modificado el Match Users a root y ahora me deja conectarme por SFTP con el usuario root.
Obviamente, a mi cliente no le voy a dar la clave root, pero me gustaría saber porque con un usuario UNIX normal no me deja conectarme por SFTP y con el root sí.
En AllowUsers tengo los dos usuarios, tanto el usuario del cliente como el del root.

La nueva configuracion es la siguiente:

# $OpenBSD: sshd_config,v 1.73 2005/12/06 22:38:28 reyk Exp $

# This is the sshd server system-wide configuration file. See
# sshd_config(5) for more information.

# This sshd was compiled with PATH=/usr/local/bin:/bin:/usr/bin

# The strategy used for options in the default sshd_config shipped with
# OpenSSH is to specify options with their default value where
# possible, but leave them commented. Uncommented options change a
# default value.
