AD Delegated user password change - powershell

Question

I'm trying to write a code in PowerShell that will loop till the user would like to exit. Thus, allowing the delegated user to change passwords for student accounts.
I have tested the code for the password change and it works without any issues.
As soon as I try adding a while loop the code wont run.
#Open powershell as Administrator
Start-process Powershell -verb RunAs
# Connect to the Domain Controller
$session = New-PSSession -ComputerName "" -Credential (Get-Credential)
Invoke-Command $session -Scriptblock { Import-Module ActiveDirectory }
Import-PSSession -session $session -Module ActiveDirectory
#verify that you're connectedto the Domain
Get-ADDomainController -Filter * | Select-Object name
#run Password Change
$userid = Read-Host -Prompt 'Please enter the studnets login ID'
$newPassword = Read-Host -Prompt 'Please enter the studnets new password'
$run = 'yes'
while ($run -eq 'yes')
{
if (Get-ADUser -Filter {SamAccountName -eq $userid})
{
Set-ADAccountPassword $userid -Reset -NewPassword (ConvertTo-SecureString -Force -AsPlainText '$newPassword')
Write - Host "$userid` password has now been changed to: $newPassword"
}
else
{
Write - Host "$userid` does not exist, please try again."
}
$answer = Read-Host -Prompt 'Would you like to change another studnets password? [y|n]'
while ($answer -notcontains 'n' -or $answer -notcontains 'N' -or $answer -notcontains 'y' -or $answer -notcontains 'Y')
{
$answer = Read-Host -Prompt 'Please answer [y|n]'
}
if ($answer -eq 'y' -or $answer -eq 'Y')
{
$run = 'yes'
}
if ($answer-eq 'n' -or $answer -eq 'N')
{
exit
}
}

PowerShell is not case sensitive by default / design. So, no need to check for that.
Based on what you are after, you have potentially over engineered this item.
I'd suggest changing this to a simple to a Do..Until.
Clear-Host
do
{
"`n"
$TargetUser = Read-Host -Prompt 'Enter a user SamAccountName'
"Processing user $TargetUser"
Get-ADUser -Identity $TargetUser
"`n"
$answer = Read-Host -Prompt 'Would you like to see another user? [y|n]'
}
until ($answer -eq 'n')
"You entered $answer. Finished processing routine."
Enter a user SamAccountName: Administrator
Process user Administrator
...
Enabled : True
GivenName :
Name : Administrator
...
SamAccountName : Administrator
...
Would you like to see another user? [y|n]: y
Enter a user SamAccountName: sqladmin
Process user sqladmin
...
Enabled : True
GivenName : SqlAdmin
Name : SqlAdmin ServiceAccount
...
SamAccountName : sqladmin
...
Would you like to see another user? [y|n]: n
You entered n. Finished processing routine.
Personally, if it were me doing this, I'd approach this a different way.
Create file on a share that can be updated with user SamAccountName
/ ID's for target changes.
Read in that file in the code.
In the code, auto generate a password.
Do whatever additional steps as needed in the code.
Thus removing all the manual prompting labor.
