# Jailkit _must_ be installed for this script to work! Even then it may not.
# You can download jailkit from: http://olivier.sessink.nl/jailkit/

# Some test variables
#company=testcompany
#passwd=test
#user=testuser

# you shouldn't need to add the company group, since the mkjail script
# should have done it for you
#groupadd ${company}

# Some default variables
jailp="/home/jail"          # Path to the jails
skelp="/etc/skel-jail"      # Path to the jail skeleton dir
                            # Set skelp to /etc/skel if in doubt

# The script should be run with a three arguments following, which should be:
# (1) the name of the company whose jail you are adding the user to,
# (2) the username you are adding, and (3) the password of said user.
company=${1}
user=${2}
passwd=${3}

# I should probably mention that this script ignores any arguments after the
