SSO for OWA 2007

Did some changes today to an existing Lotus Domino 6.x environment, in which user use iNotes (Domino Web Access) for accessing e-mail and calendar. This all worked fine, but as we are migrating from Domino/Notes to Exchange/Outlook, some modifications needed to be made to the web setup.

We used a WebSphere plug-in from IBM, to automatically authenticate Windows users to the Domino-environment. This is done by using a ISAPI filter from IBM, configured in an IIS-website, with which incoming requests on - say - port 80 in IIS are re-routed to - again, say - port 81 on the Domino webserver. The ISAPI filter passes the username from the Windows environment to the Domino server, and thus authenticates the user there. Requirement is that the fully-distinguished Windows username (DOMAIN\Username) is known in the Domino-environment. By adding this fully-distinguished Windows username to the user's Domino full name, all this got to work.

Very nice!

But, as I said, we're migrating from Domino to Exchange. And this means we're moving away from iNotes (Domino Web Access) to OWA (Outlook Web Access). Also for that, we would like to have some kind of Single Sign-on (SSO) for OWA. I did some quick googling for that, but cannot find something quickly.

So, does anyone know of a method of automatically authenticating Windows users to the web environment in Outlook Web Access? If so, let me know. (I told you how to do SSO to Domino, now tell me how to SSO to OWA :-) :-)).

Regards, Rene

Lessons Learned - Cisco ASA 5505 and TCP request discarded

Hi there, Last week, we set up a Cisco ASA 5505 firewall in one of our customers' LAN. It should replace the ISA 2000 firewall over there, because we need to create a site-to-site tunnel to a PIX 515E on a remote location. All went fine with this ASA 5505, except that it would not pass any traffic from the internet to the LAN. From the inside out, all was OK. From the outside in, nothing would pass the firewall. The relevant config lines were as follows: static (inside,outside) tcp w.x.y.z 25 10.10.10.10 25 netmask 255.255.255.255 access-list outside01 permit tcp any host w.x.y.z eq 25 access-group outside01 in interface outside So, here we redirect all SMTP traffic on public interface with IP w.x.y.z to private host 10.10.10.10. Nothing much would happen. Internally, the SMTP host was listening, of course. From outside, the interface with IP w.x.y.z was pingable, of course. From the outside, configuring the ASA with SSH or HTTPS went fine. (So, traffic TO the

Change the default telnet client

Enable handling of telnet://hostname:port/ URLs on the command line. With this feature, you can now set PuTTY as the default handler for Telnet URLs. If you run the Registry Editor and set the value in HKEY_CLASSES_ROOT\telnet\shell\open\command to be "\path\to\putty.exe %1" (with the full pathname of your PuTTY executable), you should find that clicking on telnet links in your web browser now runs PuTTY.

Printing to LPD Printer Is Slow or Fails with Windows

Experienced a nasty printing problem, which was caused by a number of ingredients that together will make it very odd that someone else will ever experience this problem, but anyway: here's the story... At a customer's site, we implemented new industrial labelprinters (Zebra's, very fine machines). Per label printing went fine to these printers, but printing a higher number of labels (> 10) showed a strange phenomenon: a number of labels printed fine, the system waited for a couple of minutes, then some labels again, then some minutes waiting again and so on... Very strange, but more important: very irritating! Other relevant infrastructure components: SAP R3 on Windows 2000 Server, printing to LPR-printers on the 2000-box, which in turn delivers the label on a print server (running Teklynx Sentinel S4 Print Pack for adding barcode functionality etc.). On this print server, the label processing is carried out and at last the label is delivered to the labelprinter. Quite
