Powershell script to create AD User

>Should contain only lower-case characters and numbers and the only special characters allowed are "_" and ".". So: ("[a-z0-9_.]")
> If there is no "." in the username, the script should ask for confirmation before creation of the user. The message should be:
"The username does not contain a dot, are you sure you want to continue?"
>Maximum amount of characters = 31
> Minimum amount of characters = 3
and how to create user in specific CN [Built in OU] with Manuel entry?

Try this script

$Regex1 = "^[a-z0-9_.]{3,31}$"

$username = "dee_."

if($username -match $Regex1)
{
    if($username -notmatch ".")
    {
        Write-host "Username doesnot contains a ., do you want to continue? (Default is No)" -ForegroundColor Yellow 
        $Readhost = Read-Host " ( y / n ) "

        Switch ($ReadHost) 
         { 
           Y {<#your logic#>} 
           N {Write-Host "No, creating user $username failed"} 
           Default {Write-Host "Default, creating user $username failed" } 
         } 
    }

}

Then it should not create user and ask to give name in valid manner like above

user name should be abc_xyz or abc.xyz or if none from both it should ask before creating any user like admin [without.,/]

Qlemo

You really should be able to do that yourself. What do you have issues with exactly? The pattern you use in your last comment and the one you showed in the origirnal question are too different to tell the desired rule.
