add existing AzureAD group to sharepoint online site with powershell

Question

I have an problem with adding existing Azure AD groups to SharePoint online. What am I trying to do, I’m creating 50+ sites and break the site inheritance. then I like to add existing AzureAD groups to the SharePoint online site

there are a lot of sites that explaine how to create a new group and add that to the site and how to add users to a group but I haven’t found an site that explains how to add an existing group to a site.

I looked at this site but this is adding users to an group Add AD group to SharePoint Online using REST API

the title of the site sounded good

I know how to do this on-prem but in the cloud there is where i have a problem

Hope someone knows the answer

Answer 1

We did the following when adding AD groups via C#:

var group = ctx.Web.EnsureUser($"c:0t.c|tenant|{groupid}");
item.RoleAssignments.Add(group, new RoleDefinitionBindingCollection(ctx) {contribute});

Where groupid was the object identifier of the AD group. If you import the SharePoint Client libraries to PowerShell, you should be able to refactor this so that you can use it.

Answer 2

I already faced this situation, the trick is to create a SP group let's name it (All AD Groups), and let's suppose we already created our AD groups (for example: ADG1, ADG2 ...etc)

in sharepoint the AD groups are considered users (not SP groups), so all you need to do is to add this AD groups to the SP group created above "All AD Groups", and you will see that your AD groups are automatically add to your site collection.
