Using PowerShell to bulk create criteria-based security groups from a CSV file

# Create criteria-base security groups from a CSV file.

# The CSV file must include a header row, such as in the following example (without the leading hashes):

#DisplayName,AccountName,Description,Filter
#SG-Geneva,sgGeneva,Staff based in Geneva,/Person[(EmployeeType = 'Employee') and (OfficeLocation = 'Geneva')]
#SG-Engineers,sgEngineers,All Engineers,/Person[(EmployeeType = 'Employee') and ((starts-with(JobTitle, 'Consultant')) or (starts-with(JobTitle, 'Technical')))]
