Check for Tenants connected with Basic Auth

Post by kavaa »

Does anyone know how to check with Powershell what tenants are connected via Basic Auth.
So we can change them over to Modern Auth.

We have over 900 Tenants in the server,,, clicking on them one by one and checking would be very time consuming.
VEEAM support is telling is there is no "Script" for it...

Hi Kay

You can try to build yourself a powershell script for the following command:
- Get-VBOOrganization
Each organization contains two properties which shows the authentication type for the tenants SPO and Exchange Online Connection:
- Office365ExchangeConnectionSettings
- Office365SharePointConnectionSettings
I don't find any other possibility in our guides for powershell.

There is another method. You can use VBO RestAPI.
This gives you the following property per organization:
- useApplicationOnlyAuth
If it's True, then no Basic Auth is leveraged for the organization. If it's False, then VBO is configured with Basic Auth for this organization.

I would probably use myself the REST APi Method.

I agree with Mildur. This is probably the easiest way to do it, through the API

Thanks with a lot of dirty scripting got it to work.
Would just be nice if VEEAM provided a script with easy output. But to bad they don't

Good afternoon,
Saw this right now, thanks to Mildur's quick point to the API, I've prepared a non-official, but quick HTML Report, that looks like this:

Everything in red should be taken care of.

It just requires:
  • Download the veeam_microsoft365_modernauth_report.sh to a Linux server that can reach the VB365 RESTful API Server. I always recommend wget to avoid copy/paste errors
  • chmod + veeam_microsoft365_modernauth_report.sh
  • Edit the Configurations, usually adding a user/pass, and email address. And the Path to the HTML Report on the Linux box needs to exist prior to you executing the Script
  • Run it, and that's it, you can find the HTML on the folder you specified, plus on your email if everything worked as expected
Small system requirements

Code: Select all

apt-get install jq

Code: Select all

apt-get install s-nail
Configure the s-nail with:

Code: Select all

vi ~/.mailrc
set smtp-use-starttls
set ssl-verify=ignore
set smtp=smtp://YOURSMTPSERVER:587
set smtp-auth=login
set smtp-auth-user="YOURUSER@YOURDOMAIN.COM"
set smtp-auth-password="YOURPASSWORD"
set from="YOURFROMEMAIL@YOURDOMAIN.COM"
As said, not official, just something to help you, and others with a similar case, which is really important as you mentioned.

Hope it helps.
