## SYNTAX

```
Get-DomainGPOUserLocalGroupMapping [[-Identity] <String>] [-LocalGroup <String>] [-Domain <String>]

 [-ServerTimeLimit <Int32>] [-Tombstone] [-Credential <PSCredential>]
```

## DESCRIPTION
Takes a user/group name and optional domain, and determines the computers in the domain
the user/group has local admin (or RDP) rights to.

It does this by:
    1. 
resolving the user/group to its proper SID
    2. 
enumerating all groups the user/group is a current part of
        and extracting all target SIDs to build a target SID list
    3. 
pulling all GPOs that set 'Restricted Groups' or Groups.xml by calling
        Get-DomainGPOLocalGroup
    4. 
matching the target SID list to the queried GPO SID list
        to enumerate all GPO the user is effectively applied with
    5. 
enumerating all OUs and sites and applicable GPO GUIs are
        applied to through gplink enumerating
    6. 
querying for all computers under the given OUs or sites

If no user/group is specified, all user/group -\> machine mappings discovered through
GPO relationships are returned.

## EXAMPLES

### -------------------------- EXAMPLE 1 --------------------------
```
Find-GPOLocation
```

Find all user/group -\> machine relationships where the user/group is a member
of the local administrators group on target machines.

### -------------------------- EXAMPLE 2 --------------------------
```
Find-GPOLocation -UserName dfm -Domain dev.testlab.local
```

Find all computers that dfm user has local administrator rights to in
the dev.testlab.local domain.

### -------------------------- EXAMPLE 3 --------------------------
```
Find-GPOLocation -UserName dfm -Domain dev.testlab.local
```

Find all computers that dfm user has local administrator rights to in
the dev.testlab.local domain.

### -------------------------- EXAMPLE 4 --------------------------
```
$SecPassword = ConvertTo-SecureString 'Password123!' -AsPlainText -Force
```

$Cred = New-Object System.Management.Automation.PSCredential('TESTLAB\dfm.a', $SecPassword)
Get-DomainGPOUserLocalGroupMapping -Credential $Cred
