Copy the membership of a given group to another group in Active Directory
#requires -Version 3.0 -Modules ActiveDirectory
function Copy-ADGroupUserMemberships
{
<#
.SYNOPSIS
Copy the membership of a given group to another group in Active Directory
.DESCRIPTION
Copy the membership of a given group to another group in Active Directory.
By default only the members of the Source Group will be copied to the Target Group.
If the Parameter FULL is used, the Memebrs of the Target Group that are not a member of the Source Group will be removed.
If the Parameter SYNC is used, the Membership is synced between both groups. If a User is Member of the Target Group only, this membership will be copied to the Source as well.
.PARAMETER SourceGroup
Source-Group Object.
Specifies an Active Directory group object by providing one of the following values. The identifier in
parentheses is the LDAP display name for the attribute.
Distinguished Name
Example: CN=saradavisreports,OU=europe,CN=users,DC=corp,DC=contoso,DC=com
GUID (objectGUID)
Example: 599c3d2e-f72d-4d20-8a88-030d99495f20
Security Identifier (objectSid)
Example: S-1-5-21-3165297888-301567370-576410423-1103
Security Accounts Manager (SAM) Account Name (sAMAccountName)
Example: saradavisreports
The cmdlet searches the default naming context or partition to find the object. If two or more objects are
found, the cmdlet returns a non-terminating error.
This parameter can also get this object through the pipeline or you can set this parameter to an object
instance.
.PARAMETER TargetGroup
Target-Group Object.
Specifies an Active Directory group object by providing one of the following values. The identifier in
parentheses is the LDAP display name for the attribute.
Distinguished Name
Example: CN=saradavisreports,OU=europe,CN=users,DC=corp,DC=contoso,DC=com
GUID (objectGUID)
Example: 599c3d2e-f72d-4d20-8a88-030d99495f20
Security Identifier (objectSid)
Example: S-1-5-21-3165297888-301567370-576410423-1103
Security Accounts Manager (SAM) Account Name (sAMAccountName)
Example: saradavisreports
The cmdlet searches the default naming context or partition to find the object. If two or more objects are
found, the cmdlet returns a non-terminating error.
This parameter can also get this object through the pipeline or you can set this parameter to an object
instance.
.PARAMETER full
Remove all memberships from the Targewt that does NOT exist in the the Source.
.PARAMETER sync
Syncronise the group membership between Source-Group and Target-Group.
Even if a user is a member of the Target-Group only, it will be copied to the Source-Group as well.
.EXAMPLE
PS C:\> Copy-ADGroupUserMemberships -SourceGroup 'Sales' -TargetGroup 'Salesforce'
Copy the membership of the Group 'Sales' to 'Salesforce'
.EXAMPLE
PS C:\> Copy-ADGroupUserMemberships -SourceGroup 'Sales' -TargetGroup 'Salesforce' -sync
Copy the membership of the Group 'Sales' to 'Salesforce' and the other way around.
All Memberships of 'Salesforce' that does NOT exist in 'Sales' will be created in 'Sales' as well.
.EXAMPLE
PS C:\> Copy-ADGroupUserMemberships -SourceGroup 'Sales' -TargetGroup 'Salesforce' -full
Copy the membership of the Group 'Sales' to 'Salesforce'.
All Memberships of 'Salesforce' that does NOT exist in 'Sales' will be removed.
