>>ASSERTION Good B 1
A call to xname
enables the use of the access control list at each connection setup.
>>STRATEGY
Get current host list.
Attempt to remove all hosts from list.
If this fails with BadAccess:
  Report that this host does not have permission to do this.
  (Will not have permission for the next part either).
  Result is untested.
Enable access control with xname.
Verify that state returned by XListHosts is EnableAccess.
Verify that new connections can not be made.

When an attempt is made to enable the use of the access control list

error occurs.

Call xname.
If error occurs.

	Report Pass.
  else
	Report Fail.

  Report client is authorised.
