# and syslog_fix_perms to a string containing "<user>:<group>"

# also note, that this will expire the password, forcing a change

#
# By default in the UEC images password authentication is disabled
# Thus, simply setting 'password' as above will only allow you to login
# via the console.
#
# in order to enable password login via ssh you must set
# 'ssh_pwauth'.
# If it is set, to 'True' or 'False', then sshd_config will be updated
# to ensure the desired function. If not set, or set to '' or 'unchanged'
# then sshd_config will not be updated.

# there is also an option to set multiple users passwords, using 'chpasswd'

# chpasswd:
# list: |
# user1:password1
# user2:RANDOM
# expire: True
# ssh_pwauth: [ True, False, "" or "unchanged" ]
