Powershell output file missing SamAccountName results - powershell

Question

New to powershell, and I can't figure out why the SamAccountName column in the output file is empty. while the IsDisabled column has the account status results.
Import-Csv $filename | Foreach-Object{
$user = ([ADSISEARCHER]"(samaccountname=$($_.SamAccountName))").FindOne()
if($user)
{
New-Object -TypeName PSObject -Property #{
SamAccountName = $user.SamAccountName
IsDisabled = $user.GetDirectoryEntry().InvokeGet('AccountDisabled')
}
}
else
{
Write-Warning "Can't find user '$($_.SamAccountName)'"
}
} | Export-Csv $filename

Answer 1

You have to change the 6th line to:
SamAccountName = $user.Properties.samaccountname

Answer 2

You need to specify sAMAccountName as one of the properties to return. In addition you can specify the userAccountControl property and test the ADS_UF_ACCOUNTDISABLE bit to see if the user account is disabled. This will avoid the overhead of binding to each user object to test if disabled. Here is a short sample script:
param(
[String[]] $sAMAccountName
)
$ADS_UF_ACCOUNTDISABLE = 2
$sAMAccountName | foreach-object {
$searcher = [ADSISearcher] "(sAMAccountName=$($_))"
$searcher.PropertiesToLoad.AddRange(#("samaccountname","useraccountcontrol"))
$result = $searcher.FindOne()
if ( $result ) {
$samName = $result.Properties["samaccountname"][0]
$disabled = ($result.Properties["useraccountcontrol"][0] -band
$ADS_UF_ACCOUNTDISABLE) -ne 0
new-object PSObject -property #{
"Name" = $samName
"Disabled" = $disabled
}
} else {
write-warning "Can't find user $_"
}
}

IIRC this is a known issue (bug) with case-sensitive ldap property names. To avoid that you can use the hashtable syntax and not worry about case:
$user.Properties['SAMACCOUNTNAME']
