<disclaimer> This is really not the forum for this, but it's come up before, and I don't have an answer for it. On the other hand, this is the most astute list or newsgroup I've read pertaining to Windows networking, so here goes... </disclaimer> Using Samba 1.9.18p8, HPUX 10.20 and Win95 clients, we have W95 configured to require a domain logon, and as far as that goes it's working. We're set up on four servers, on four different campuses, each defined as a PDC and it's own "domain". We use /etc/passwd for authentication. At login, if a valid accountname, password, and domain are entered, everything's just peachy. And yes, we've used poledit to require validation by network for windows access. However. We've been using Tweakui to clear the last user's login name, to minimize user confusion in our public labs. The unfortunate side effect of this is that now it is possible to enter any accountname/ password pair *and a bogus domain name*, and get access to the computer and the network. This is exactly the opposite behavior to what one would expect, and seems to us to be a gaping security hole. Note, however, if the accountname is *not* stripped before the next user logs on, then a bogus domain *fails* login, an error message is displayed, and everything works fine. Weird. Adding a %windir%\system\wrkgrp.ini file doesn't do what we want, as we need to allow roaming users to logon to their home domains. A drop-down box for the domain field in the logon box would be perfect, especially if it could be controlled the way wkrgrp.ini controls the network control panel applet. Is there an API or some other hook (.ini file, registry key, magic incantation) that would help? I've searched the Technet CD and MS' support site to no avail. c -- Clifford Green Internet - green@umdnj.edu Academic Computing Services voice - 732-235-5250 UMDNJ-IST fax - 732-235-5252 c -- Cliff Green green@umdnj.edu Academic Computing Services University of Medicine and Dentistry of New Jersey
