 1. Create a new SSH connection from your console. Use a domain account that belongs to the managed domain using the `ssh -l` command, such as `[email protected]` and then enter the address of your VM, such as *centos.aaddscontoso.com*. If you use the Azure Cloud Shell, use the public IP address of the VM rather than the internal DNS name.

-    ```console
-    pwd
+    ```bash
+    sudo pwd

     You should be in the */home* directory with your own directory that matches the user account.
 
 1. Now check that the group memberships are being resolved correctly:
 
-    ```console

     You should see your group memberships from the managed domain.
