1407.0. "Proxy and wildcards (OBB V2.7-11 on VMS)" by RULLE::KLASSON (Sven-Olof Klasson @GOO) Thu May 22 1997 16:54

Hi,

Why does not this command work (VMS and Objectbroker V2.7-11)?

  OBB> ADD PROXY KLASSON/REMOTE=(USER=KLASSON,HOST=*)
  %OBB-E-CMD_BADPROXYWIL, Invalid proxy wildcard.

These commands works

  OBB> ADD PROXY KLASSON/REMOTE=(USER=*,HOST=*)
  OBB> ADD PROXY KLASSON/REMOTE=(USER=*,HOST=RULLE)

A customer wan't to use wildcard for HOST only. He has 800 users and they may
login an any of 300 PC's. He wan't to have the same username in Windows and
VMS. But allow any host.

Why can't a wildcard by used for HOST?

This is a feature. See page 3-2 of the Commands and Utilities Reference
manual.  If you wildcard the host, then the username MUST ALSO be
wildcard. In other words, all users on the remote hosts map into
the localuser specified.

    The combination of explicit remote user and wildcard remote host is
    specifically disallowed by the command line interface code. I also
    believe the combination is not checked for at runtime when looking for
    applicable proxies (I forced the illegal combination into the security
    registry, but it wasn't picked up during a proxy check).
    
    The history behind the decision to disallow this combination is vague.
    You could make a formal request for this functionality through
    the product manager...

	Does the customer have physical security of their entire network
	(ie. no one could plug in a laptop or handheld computer into
	the network)?

	The problem with wildcarding the hostname is that it makes it even
	easier than it already is to gain unauthorized access to the server.

	But if the customer is sure their physical network is secure, and
	has system management control of all the systems, then I agree
	with Bill, give them the rope .....

    Hi,
    
    Thanks for the replies.
    I have recommended the customer to use the following proxy
    OBB> add proxy * /remote=(user=*,host=sprutt)
    
    I tried it and it seems to match the same local username as
    the username on the remote host.
