# The configuration of the sshd is rather strict and
# might not fit all needs. However there are a bunch
# of variables, which you might consider to configure.
# Checkout the following:
#
# sshd_allowed_users: list of usernames separated by spaces.
# set this for example to "foobar root"
# to ensure that only user foobar and root
# might login.
# Default: empty -> no restriction is set
#
# sshd_use_pam: if you want to use pam or not for authenticaton
# Values: no or yes.
# Default: no
#
# sshd_permit_root_login: If you want to allow root logins or not.
# Valid values: yes, no, without-password, forced-commands-only
# Default: without-password
#
# sshd_password_authentication: If you want to enable password authentication or not
# Valid values: yes or no
# Default: no
#
# sshd_x11_forwarding: If you want to enable x11 forwarding
# Valid Values: yes or no
# Default: no
