## DESCRIPTION
Uses Get-DomainGroup to enumerate all groups for the current (or target) domain,
then enumerates the members of each group, and compares the member's domain
name to the parent group's domain name, outputting the member if the domains differ.

## EXAMPLES

### -------------------------- EXAMPLE 1 --------------------------
```
Get-DomainForeignGroupMember
```

Return all group members in the current domain where the group and member differ.

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

Return all group members in the dev.testlab.local domain where the member is not in dev.testlab.local.

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

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

Return all group members in the dev.testlab.local domain where the member is
not in dev.testlab.local.
binding to the secondary.dev.testlab.local for
queries, and using the specified alternate credentials.
