On September 12th, 1996 the DCE Users Group of Michiganmet
at the University of Michigan's Center for Information
Technology Integration (CITI).The meeting was sponsored by
Exchange", A joint partnership of IBM and the University of Michigan promoting
open, client/server computing.
Hosting the meeting was Janani Janakiraman of UofM/CITI. Brad
Smart - Nortel, volunteered to take the minutes.
The agenda of the meeting was as follows:
- Janani: New Focus for this group
- Bob Riddle: U-M CITI - Big 10 Joint Project
- Jonathan Chinitz (Intellisoft, Chairman DCE SIG) :
-- DCE/Snare, A transparent security gateway for
Kenn Dany - Chrysler, Michael Leekofsky - Wayne State, Al
Johnson - Chrysler,Brad Smart - Northern Telecom, Alex F. -
Chrysler, Tish Lehman - U/M, Neda Gholizadeh - U/M, Lisa Wyatt-
EDS, Tim Campbell - EDS, Gary Pirkola - UM/ITD,Dave Detlefs
--UM/ITD, Craig Berkowitz - Transarc, Ian Smart - Ford, Steve
Freeman - IBM, Ik Kim - Chrysler, Mary Pearce - U/M, Zoe Gurevich
-- U/M, Krishnam Subraminam - Ford, Bob Brandt - Ford, John Kroll
- Ford, Janani Janakiraman - UM-CITI.
The next meeting will be on November 14, 1996.
- OSF RI DCE related activities ...... Tom Sanfillipo, OSF
- Praseidium ..... Hewlett Packard
The first order of business was the new focus of the group.
This group is currently sponsored by Client Server Exchange. At
the end of this year CSE will end. Should this group dissolve or
change focus and continue?
Craig Berowitz suggested that the group increase its scope to
include other client server technologies in addition to DCE. Lisa
Wyatt suggested that we focus on DCE + WEB + OOT. There was some
additional discussion, but no conclusions. Janani suggested that
this will be decided at the November 14 meeting. Please send your
feedback on this to Janani at <firstname.lastname@example.org>.
Big 10 Joint Projects
Bob Riddle spoke on the Big 10 Joint Projects. A Web page for
these projects is at:http://usfs2as.us.ohio-state.edu/big10/btjp.htm.Bob
explained a little about the project team. He said it primarily
is a cross institutional team of technical "gadflys"
looking at technology for the future. Bob talked about three
separate projects involving DCE:
- This is a project for securely transmitting student
transcripts between universities. It requires a DCE cell
at each campus.
- The purpose of this project is to develop a secure web
architecture for transaction processing on the web
utilizing Gradient's DCE-Web and SDG products, Netscape
SSL, NCSA Basic Authentication, Kerberos, and other
A CIC (Committee on Institutional Co-operation) project for
library resource access by authorized users. I did not catch the
name of this project.
- Is there a way to leverage investments between
- Make traditional materials available electronically - but
enforce user authentication - and licensing (charge for
services).These could be electronic copies of journals,
etc. (use your imagination).
- No assumptions can be made about the browser on the
client or the "content provider" (server).
Neither can be required to have DCE runtimes installed.
- How to identify that a person is authorized for access
without having to duplicate all user ids in every domain.
Basically, has someone "vouched" for you? Local
credentials will actually be mapped into a very small
number (1-3) of credentials at the client end and placed
into a special "EPAC" for transmission. DCE
will only be required at the outer "edges" of
the participating networks, not on the actual browser or
the actual "content provider" (although nothing
precludes its being there either).
- Some of this went over my head. There seemed to be a lot
of interest, and there was Q&A with Bob and a lot of
discussion. Basically, the goal is to prove:
- An "Inter-Institutional Authentication
- There is a CIC projects page at " http://www.cic.net/projects.html
IntelliSoft Corporation was founded in 1992. It is a DCE
focused company. Up until this year their business has been DCE
training and consulting. 1996 marks the introduction of their DCE
product line. IntelliSoft's web page is http://www.isoft.com/.
- A Transparent Security Framework for TCP/IP and Legacy
- TCP/IP has become the de facto standard
- TCP/IP is not a secure protocol.
- Corporations require scaleable, reliable, interoperable
- DCE/Snare™ allows existing TCP/IP applications to
leverage DCE security framework with 100% transparency.
- Provides capability for Virtual Private Networks (VPNs).
- Requires absolutely no application changes.
- Jonathan went into a lot of detail on architecture of the
product. The slides will be made available electronically
at this web site. The white paper which was provided to
attendees can be found at:http://www.tiac.net/users/jec/snarewp/snarewp1/snarewp1-contents.html.
- There was a lively Q&A following the presentation
with no time left to discuss DCE/Sleuth™. Handouts
