# Managing Active Directory users and groups from PowerShell without scanning the whole directory

Get-ADUser with -Filter and -Properties, New-ADUser with a SecureString password, Add-ADGroupMember, and Search-ADAccount/Unlock-ADAccount for lockouts — plus why -Filter * is a trap in a directory with tens of thousands of objects.

## Goal
Read, create, and unblock Active Directory user and group objects from PowerShell using the ActiveDirectory module, scoped so a call against a large directory does not become an unbounded scan.

## Prerequisites
The ActiveDirectory PowerShell module (from RSAT or installed on a domain controller); rights to read the target OU, and Account Operators or delegated write rights to create or unlock accounts.

## Steps
1. Query with a real filter and only the properties needed: `Get-ADUser -Filter "Department -eq 'Finance'" -Properties Mail,Title -SearchBase "OU=Users,DC=contoso,DC=com"`. The module's own reference shows `Get-ADUser -Filter *` as the everything-matches form — useful for a small OU, but on a directory with tens of thousands of objects it pulls every user object and every default property across the wire; always add `-SearchBase` and a specific `-Filter`, or `-LDAPFilter` for complex conditions.
2. Create an account non-interactively with the password supplied as a SecureString: `$pw = ConvertTo-SecureString "TempP@ssw0rd!" -AsPlainText -Force; New-ADUser -Name "Jane Doe" -SamAccountName jdoe -UserPrincipalName jdoe@contoso.com -AccountPassword $pw -Enabled $true -ChangePasswordAtLogon $true`. The literal is for illustration only — it lands in history and transcripts; in real runs read it from a secret store. Do not name the variable `$pwd`, which is PowerShell's automatic current-location variable. If the password violates the domain policy, the account is created but left disabled.
3. Add the new account to a group: `Add-ADGroupMember -Identity "Finance Team" -Members jdoe`.
4. Find locked-out or stale accounts across the domain: `Search-ADAccount -LockedOut` and `Search-ADAccount -AccountInactive -TimeSpan 90.00:00:00 -UsersOnly`; both accept `-SearchBase` to scope the search. Inactivity is judged from the replicated `lastLogonTimestamp`, which can lag real logons by up to about two weeks.
5. Clear a lockout: `Unlock-ADAccount -Identity jdoe`.

## Expected result
`Get-ADUser` returns only the scoped result set; the new account authenticates and is prompted to change its password at first logon; `Search-ADAccount -LockedOut` no longer lists the account after `Unlock-ADAccount`.

## Limits and test basis
`-AccountPassword` on `New-ADUser` is documented to take a SecureString, not a plain string — passing plain text fails the parameter binding. To undo account creation, `Remove-ADUser -Identity jdoe -Confirm:$false`. A deleted account can only be brought back with its SID and memberships through `Restore-ADObject` when the AD Recycle Bin was enabled before the deletion; an `Export-Clixml` dump of its attributes is only a reference — recreating from it yields a new SID. None of these operations require a reboot; changes must first replicate to the domain controller the client uses, and group membership changes reach a user's access token only at the next sign-in (or, for network resources, after the Kerberos tickets are purged and reacquired), not in an already-open session.
