A small script to add users to an AD environment based off a CSV file. More detail in my website - www.parkisecurity.com

.SYNOPSIS

.DESCRIPTION

.PARAMETER CSVPath

.INPUTS
None
You cannot pipe objects to this cmdlet
.OUTPUTS
Various and sundry.
.NOTES
bite me
.EXAMPLE
Kansa.ps1
In the above example the user has specified no arguments, which will
cause Kansa to run modules per the .\Modules\Modules.conf file against
a list of hosts that it is able to query from Active Directory. Errors
and all output will be written to a timestamped output directory. If
.\Modules\Modules.conf is not found, all ps1 scripts starting with Get-
under the .\Modules\ directory (recursively) will be run.
