Populating Test Labs with User Accounts…

Those of you that have been following this blog will know that recently I have made a number of posts that are either based around the virtues of Test Labs or indeed that work that I have been doing in relation to them – for information my posts on the subject are here, here, here, here and finally here.

Now one of the most daunting things about test labs, is not always the construction of the Domain, or indeed the creation of the servers within them, but how to you populate them with any meaningful user data as part of the Directory (e.g. creating a number of users).

In this article I would like to provide all of you with the following tools that will help you construct the users in your test lab:

  • A CSV file with 389 unique users within it – this files contains the following data FirstName, Surname, samAccountName, Display Name, Password, and a UserPrincipleName
  • A VBSCRIPT that will parse the data in the CSV file and create 389 users account in your test LAB which are ready to be used as part of either an Exchange 2003 or Exchange 2007 test lab

Before I begin (and if you are interested in using this article) you will need to download the following files to your Exchange server or domain controller in your LAB:

LabUsers.csv – 389 Fictonal People just for you!

LAB_CreateUsers.vbs – the script that parses the CSV file and creates the file in your directory.

When you have downloaded them place them in a Directory Called “LBUsers

Then create a new Organizational Unit in Active Directory called “ExchangeUsers” – it is easier to make this OU in the root of your AD structure, however, the script can handle nested OU’s as well.

What you will need to do now is modify the UPN (User Principle Name) for all users within the csv file – now, don’t panic you do not have to go through all 389 users – all you need to do is:

Open the CSV file on your server in NOTEPAD – then go to the Edit menu and select the replace option – see below

When the replace dialog box appears in the “Find What” area type in: “@ldn.com” (without quotes) and then in the “Replace with” area type in the name of your test domain – “@” (without quotes) – so if you had a test domain called @billy.com, billy.com is what you would type into the “Replace with” area – see below

Click on the “Replace All” button, NOTEPAD will then go away and replace all entries with the values that are relevant to your test lab domain.

When NOTEPAD is finished – save the file.

When you are happy with the content of the CSV file you can begin by double clicking on the Lab_CreateUsers.vbs file – which when first launched will prompt you for the following information:

sc1

Enter in the full path to the CSV file (do not enter in the file name) and ensure that you add in the trailing slash for the path – then click the “OK” button.

sc2

You will then be presented CSV filename dialog box – enter in LabUsers.csv and then click on the “OK” button.

sc3

Then you will be prompted for the target OU that you wish to use this should be entered in the format of “OU=ExchangeUsers” (without quotes) – if you have placed your OU inside a parent OU then the format will change to “OU=ExchangeUsers,OU= ” – again without quotes.

When you are happy with your OU settings click on the “OK” button.

sc4

When the script has completed, you will be presented with the dialog box above – go to Active Directory Users and Computers and navigate to the OU that you created and you should see something similar to the following:

sc5

At the end of this process you should now have 389 users, in an OU called “ExchangeUsers” ready to be part of your test lab.

For reference the following is the contents of the LAB_CreateUsers.vbs script:

strCSVPath = InputBox(”Please enter in the full path to your CSV (PLEASE INCLUDE THE END SLASH \)”)
strCSVName = InputBox(”Please Enter in the FileName”)
strOU = InputBox(”Please Enter in the destination OU (FORMAT: OU=,OU=”)

set csvInputConn = createobject(”ADODB.connection”)
set csvInputRS = createobject(”ADODB.recordset”)

csvInputConn.Open “Provider=Microsoft.Jet.OLEDB.4.0;” & “Data Source=” & strCSVPath & “;” & “Extended Properties=”"text;HDR=NO;FMT=Delimited”"”
csvInputRS.open “SELECT * FROM ” & strCSVName,csvInputConn

Set RootLDAP = GetObject(”LDAP://rootDSE“)
Set ADLocation = GetObject(”LDAP://” & strOU & “,” & RootLDAP.Get(”defaultNamingContext”))

do until csvInputRS.EOF
On Error Resume Next
strFirstName = csvInputRS.Fields.Item(0).value
strSurName = csvInputRS.Fields.Item(1).value
strSam = csvInputRS.Fields.Item(2).value
strDisplayName = csvInputRS.Fields.Item(3).value
strPassword = csvInputRS.Fields.Item(4).value
strUPN = csvInputRS.Fields.Item(5).value

Set strUser = ADLocation.Create(”User”,”cn=” & strSam)

strUser.put “sAMAccountName”,strSam
strUser.put “givenName”,strFirstName
strUser.put “sn”,strSurname
strUser.put “UserPrincipalName”,strUPN
strUser.put “DisplayName”,strDisplayName
strUser.put “name”,strDisplayName
strUser.put “mail”,strUPN
strUser.SetInfo
strUser.SetPassword sPassword

strUser.Put “userAccountControl”, 512
strUser.SetInfo

csvInputRS.movenext

Loop

WScript.Echo “Script Completed - Hit F5 in the OU that you selected”
WScript.Quit
