## To Reproduce:

- _Put any pre-requisite steps here..._
- `az login --service-principal --username {} --password {} --tenant {}`

## Expected Behavior
To be able to use a service account (SPN) for enumerating resources within azurestack. We don't use any certificates, only SPN's values are passed along the command line.

Before upgrading to 2.30.0, we were using 2.29.x and the same command line worked. As of now, we had rolled back to AZ version 2.29.0 and it does the job..
