# This file must be executable to work! chmod 755!
#
# And amended by Richard Brown 13/4/2008.
# added a check for a default credentials file
# format of credentials file is:
#   username = <name>
#   password = <password>
#   domain = <domain> 
# as this file has secret suff ie a password and only needs to be accessed by root 
# change the permissions to chmod 600!
