Hello,

Im using a business rule triggered before a new user is created to check for username uniqueness. Our company continues to add characters from the first name to build out a unique user name. For example Jdoe, Jodoe, JohDoe,etc.

I'm using the script referenced here: Unique Username
This script appears to be designed to do something similar, except that the first name is at the end of the username.
I modified the script to:

if (($firstName -ne $NULL) -and ($lastName -ne $NULL))
{
    $username = $lastName
    foreach ($char in $firstName.ToCharArray())
    {
        $username = "$char$username"
        if (IsUserNameUnique($username))
        {
            $uniqueUsername = $username
            break
        }
    }
}

however, it builds the first name backwards. Like Jdoe, oJDoe, hoJDoe.

What can I do to fix this?

Hello,

This one should work:

if (($firstName -ne $NULL) -and ($lastName -ne $NULL))
{
    $firstNamePart = ""
    foreach ($char in $firstName.ToCharArray())
    {
        $firstNamePart = $firstNamePart + $char
        $username = "$firstNamePart$lastName"
        if (IsUserNameUnique($username))
        {
            $uniqueUsername = $username
            break
        }
    }
}
