## DESCRIPTION
Uses Get-DomainUser to enumerate all users for the current (or target) domain,
then calculates the given user's domain name based on the user's distinguishedName.
This domain name is compared to the queried domain, and the user object is
output if they differ.

## EXAMPLES

### -------------------------- EXAMPLE 1 --------------------------
```
Get-DomainForeignUser
```

Return all users in the current domain who are in groups not in the
current domain.

### -------------------------- EXAMPLE 2 --------------------------
```
Get-DomainForeignUser -Domain dev.testlab.local
```

Return all users in the dev.testlab.local domain who are in groups not in the
dev.testlab.local domain.

### -------------------------- EXAMPLE 3 --------------------------
```
$SecPassword = ConvertTo-SecureString 'Password123!' -AsPlainText -Force
```

$Cred = New-Object System.Management.Automation.PSCredential('TESTLAB\dfm.a', $SecPassword)
Get-DomainForeignUser -Domain dev.testlab.local -Server secondary.dev.testlab.local -Credential $Cred

Return all users in the dev.testlab.local domain who are in groups not in the
dev.testlab.local domain, binding to the secondary.dev.testlab.local for queries, and
