Search if a list of users already exists

Question

Hello,

I need to check, from a csv file, if users exist or not.
I do not have the login name but only the atributs Name givenName
The output must be another csv file with a column "exists" --> False or True

Is there an Adaxes script existing doing this?

Thanks in advance!

Hello,

You can use the below script. To execute it, create a Scheduled Task configured for Domain-DNS object type and add a domain to the Activity Scope. The task will create a CSV file containing a column specifying whether a user with such a name is present in your environment. In the script:

• $sourceCSVFilePath – specifies the path to the source CSV file;
• $targetCSVFilePath – specifies the path to the resulting CSV file;
• $identityColumnName – specifies the name of the column in the source file that store names of users;
• $identityPropertyName – specifies the LDAP name of the property whose values will be compared to the values stored I the columns specified in the $identityColumnName variable;
• $statusColumnName – specifies the name of the column that will store user account statuses in the resulting CSV file.

$sourceCSVFilePath = "\\Server\Share\Users.csv" # TODO: modify me
$targetCSVFilePath = "\\Server\Share\Report.csv" # TODO: modify me
$identityColumnName = "Name" # TODO: modify me
$identityPropertyName = "name" # TODO: modify me
$statusColumnName = "Exists" # TODO: modify me

# Import CSV
$records = Import-Csv -Path $sourceCSVFilePath

# Specify settings for user search
$searcher = $Context.BindToObject("Adaxes://RootDSE")
$searcher.PageSize = 500
$searcher.VirtualRoot = $True

$usersFromCSV = @{}
$filter = New-Object "System.Text.StringBuilder"
foreach ($record in $records)
{
    $userIdentity = $record.$identityColumnName
    $record | Add-Member -MemberType NoteProperty -Name $statusColumnName -Value "False"
    $usersFromCSV.Add($userIdentity, $record)

    [void]$filter.Append("($identityPropertyName=$userIdentity)")
    $remainder = 0
    [void][System.Math]::DivRem($i, 500, [ref]$remainder)
    if ((($i -ne 0) -and ($remainder -eq 0)) -or ($i -eq $importedUsers.Length - 1))
    {
        # Search users
        $searcher.SearchFilter = "(&(sAMAccountType=805306368)(|" + $filter.ToString() + "))"
        try
        {
            $searchResultIterator = $searcher.ExecuteSearch()
            $searchResults = $searchResultIterator.FetchAll()

            foreach ($searchResult in $searchResults)
            {
                $userIdentity = $searchResult.Properties[$identityPropertyName].Value
                if ($usersFromCSV[$userIdentity] -eq $NULL)
                {
                    continue
                }

                $usersFromCSV[$userIdentity].$statusColumnName = "True"
            }
        }
        finally
        {
            # Release resources
            if ($searchResultIterator) { $searchResultIterator.Dispose() }
        }

        # Clear filter
        $filter.Length = 0
        $filter.Capacity = 0
    }
}

$usersFromCSV.Values | Export-Csv -Path $targetCSVFilePath -NoTypeInformation
