    test_smb: test that we can auth as NetBIOS alias
    
    cifs/... principal on SMB server side has NetBIOS name of the SMB server
    as its alias. Test that we can actually initialize credentials using
    this alias. We don't need to use it anywhere in Samba, just verify that
    alias works.
