.SYNOPSIS
New-LabUsers.ps1 - PowerShell script to populate a test lab with user accounts
.DESCRIPTION
This PowerShell script will populate Active Directory in a test lab environment
with a set of OUs and user accounts based on randomly selected names and values.
.OUTPUTS
Results are output to console as the script is running.
.PARAMETER InputFileName
Use this parameter if you need to specify a different text file name containing
the list of users. A generated list of names is also provided with the script.
.PARAMETER PasswordLength
Use this parameter if you need to specify a different password length. By default
all the user accounts are created with a randomly generated password that is 16
characters long. You can reset the password for any user that you want to log on
with.
.PARAMETER OU
Use this parameter if you want to name the top-level OU something different than
the default name of "Company".
.EXAMPLE
.\New-LabUsers.ps1
Uses the RandomNameList.txt file to generate the list of user accounts in an OU
called "Company" in Active Directory.
.EXAMPLE
.\New-LabUsers.ps1 -InputFileName .\MyNames.txt -PasswordLength 8 -OU TestLab
Uses the MyNames.txt file to generate the list of user accounts in an OU
called "TestLab" in Active Directory.
