Checking for Unique Usernames

Question

I need some help checking for unique usernames and changing them when they are found. I followed the tutorial and it looks like the script is working but as you can see the image below that the page is never submitted and can’t be. Any idea what or where I should be looking?

Jim

Import-Module Adaxes
function IsUserNameUnique($username)
{
$user = Get-AdmUser $username -erroraction silentlycontinue
return $user -eq $Null
}
# Get the username
$username = $Context.GetModifiedPropertyValue("samAccountName")
# Check if the username is unique
if (IsUserNameUnique($username))
{
return
}
# If the username is not unique, generate a unique one
$uniqueUsername = $Null
for ($i = 1; $True; $i++)
{
$uniqueUsername = $username + $i;
if (IsUserNameUnique($uniqueUsername))
{
break
}
}

# Update User Logon Name (pre-Windows 2000)
$Context.SetModifiedPropertyValue("samAccountName", $uniqueUsername)

# Update User Logon Name
$upnSuffix = $Context.GetObjectDomain("%distinguishedName%")
$userLogonName = $uniqueUsername + "@" + $upnSuffix
$Context.SetModifiedPropertyValue("userPrincipalName", $userLogonName)
$Context.LogMessage("The username has been changed to " + $userLogonName `
+ ".", "Information")

Hello Jim,

The script is OK and works fine judging by the screenshot. The thing is in the user's Full Name property. A user's Full Name is also used as the Name property of the user account. Active Directory does not allow two objects that have identical RDNs be located in the same OU or container. The error message means that you have a user with the same RDN (that is, the same Full Name) in the same OU where you create the new user. If you create two users with the same Full Name in different OUs, Active Directory will allow you to do that as long as their usernames are different.

As an option, you can update the script for unique usernames and add code that also automatically changes the Full Name to make it unique within an OU. If you want, we can help you with such a script.

Thanks, help with a script would be great. Ideally I'd like a space and number added after the user's last name.

Thanks

Hello Jim,

An example of such a script can be found in the same tutorial where you've found the script for unique usernames. Take a look at Example 3 in the tutorial: http://www.adaxes.com/tutorials_Simplif ... Script.htm.

The script generates a unique username by adding a digit after the full name. To additionally add a space before a digit, find the following line in the script:

$objectName = $objectLeaf.Value + $i;

and replace it with the following line:

$objectName = $objectLeaf.Value + " " + $i
