Problem

A bit of context here … I was trying to create an environment in which to write an extension around workflows and notifications.

I needed 2 users, one to generate the document and the other one to receive the notification to approve it.

I decided to create a local Business Central sandbox and point my extension to this environment.

So I ran the New-NavContainer cmdlet as below

When I try to create the user as a local Windows user in the host, and in the Business Central sandbox the username gets translated into the SID for that Windows:

And after I logged as the new local user, launching BC sandbox Client it fails:

Then I’ve seen someone recommending to run New-NavContainerNewUser … so I gave it a try:

This is the issue and I have not been able to find a solution yet.

Workaround

Create the sandbox with “-Auth NavUserPassword” like below:

You will be prompted for credentials of the first user (I named mine svi) when you run the script.

The cmdlet New-NavContainer will create among many other things, a sql login with sysadmin server role.

Once the script is finished, launch BC Sandbox client, use the credentials entered at installation and create a new user.

Now I have 2 users and can continue my tests on Workflows/Approvals:

If you have a solution for a local BC sandbox with Credential Type (-Auth param in New-NavContainer) set to Windows and the issue expressed in the title, please leave a comment with your solution.

Otherwise, I hope this workaround can help anyone with the same issue.
