I try to change the script from Report 'Inactive users' to get only users which are located under an specific "Admin" OU.

I can't use "Look in" because we manage 20 small Domains and I can only pick one Admin OU at a time.
So I try to change the filter part, add $filterAdminOU = "(ou:dn:=Admin)" -> didn't work.
I can't find the failure :(

# Build search filter
$threshold = (Get-Date).AddDays(- $days)
$thresholdInt64 = $threshold.ToFileTime()
$thresholdGeneralizedTime = [Softerra.Adaxes.Utils.Transform]::ToGeneralizedTime($threshold.ToUniversalTime())

$filterUsers = "(sAMAccountType=805306368)" # all user objects
$filterAdminOU = "(ou:dn:=Admin)"
$filterCreatedBefore = "(whenCreated<=$thresholdGeneralizedTime)"

$filterNoLastLogonTimestamp = "(!(lastLogonTimestamp=*))"
$filterLoggedOnBeforeTimestamp = "(lastLogonTimestamp<=$thresholdInt64)"

# The report is based on the lastLogonTimestamp attribute, which is replicated across all DCs.
# The lastLogon attribute is not replicated but contains the exact time when a 
# user logged on the DC Adaxes is connected to. Using the attribute in search filter makes
# report results more accurate.
$filterNoLastLogon = "(!(lastLogon=*))"
$filterLoggedOnBefore = "(lastLogon<=$thresholdInt64)"

$filterPasswordChangedBefore = "(pwdLastSet<=$thresholdInt64)"

$filter = "(&" +
    $filterUsers + $filterCreatedBefore + $filterAdminOU +
    "(|" + $filterNoLastLogonTimestamp + $filterLoggedOnBeforeTimestamp + ")" +
    "(|" + $filterNoLastLogon + $filterLoggedOnBefore + ")" +
    $filterPasswordChangedBefore + ")"

Ok, I found "Support for Extensible Match Search Filters are limited, Microsoft's Active Directory for instance does not support this (reference)."

Can I filter the search result like in Powershell | where { $_.CanonicalName -like "*/Admin/*" }

Hello Helmut,

To achieve what you need, we recommend using a Business Unit as the report scope. For information on how to create Business Units, have a look at the following tutorial: https://www.adaxes.com/tutorials_Active ... tively.htm. The Business Unit should contain the users located in the Admin OUs in all the domains.

We manage employee user accounts in our on-premise Active Directory and synchronize them to Azure Active Directory using Azure AD Connect. We'd like to be able to generate ... if this is possible so we can easily identify user accounts that are truly inactive.

Hello, The report named Inactive users allowed to log in shows the Active Directory sign-in (Last-Logon-Timestamp) and Azure AD sign-in (Last Logon) but only for Active Directory ... updated by an Azure logic App. But we'd love to have this natively in Adaxes.
