## SYNTAX

```
Add-DomainGroupMember [-Identity] <String> -Members <String[]> [-Domain <String>] [-Credential <PSCredential>]
```

## DESCRIPTION
First binds to the specified domain context using Get-PrincipalContext.
The bound domain context is then used to search for the specified -GroupIdentity,
which returns a DirectoryServices.AccountManagement.GroupPrincipal object.
For
each entry in -Members, each member identity is similarly searched for and added
to the group.

## EXAMPLES

### -------------------------- EXAMPLE 1 --------------------------
```
Add-DomainGroupMember -Identity 'Domain Admins' -Members 'harmj0y'
```

Adds harmj0y to 'Domain Admins' in the current domain.

### -------------------------- EXAMPLE 2 --------------------------
```
$SecPassword = ConvertTo-SecureString 'Password123!' -AsPlainText -Force
```

$Cred = New-Object System.Management.Automation.PSCredential('TESTLAB\dfm.a', $SecPassword)
Add-DomainGroupMember -Identity 'Domain Admins' -Members 'harmj0y' -Credential $Cred

Adds harmj0y to 'Domain Admins' in the current domain using the alternate credentials.

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

$Cred = New-Object System.Management.Automation.PSCredential('TESTLAB\dfm.a', $SecPassword)
$UserPassword = ConvertTo-SecureString 'Password123!' -AsPlainText -Force
New-DomainUser -SamAccountName andy -AccountPassword $UserPassword -Credential $Cred | Add-DomainGroupMember 'Domain Admins' -Credential $Cred

Creates the 'andy' user with the specified description and password, using the specified
alternate credentials, and adds the user to 'domain admins' using Add-DomainGroupMember
and the alternate credentials.
