We recently added another domain to our environment, when we use the script to create users from a CSV file they are all being created in the first domain instead of the proper one.   
Ex. User a works for Acme and their username is a123456 and needs to go to the Acme domain for staging.
User b works for Bozo and their username is b123456 and needs to go to the Bozo domain for staging.  
We need to know how the script below can trigger where to create the account domain wise based on attribute we setup. Thinking is company attribute. We do have several trigger after creation but they are specific to certain attributes.   
Please advise.
