Where does the AD mailing list lives? I'm really interested in this as well. -Devon -----Original Message----- From: Michael B.

Exchange uses the built-in capabilities of A/D-IIS. I think you'll probably get a better response from the activedir mailing list. (I could be wrong, and somewhere here knows the answer, but I don't think so.) Ah... I see that you also posted the same question there already. -----Original Message----- From: m1r4cle_26@xxxxxxxxx [mailto:m1r4cle_26@xxxxxxxxx] Sent: Friday, August 27, 2004 2:43 PM To: [ExchangeList] Subject: [exchangelist] how kerberos authe actually works in owa 2003 http://www.MSExchange.org/ Hi, Can anyone help me to confirm whether the following flow of kerberos authentication for OWA 2003 is correct ? I can only In the directory security tab, I only enabled integrated windows authentication for exchange web site. Let's say there are 3 parties involved: - AD (in windows 2000 server) - Exchange Server 2003 - Windows XP as a testing client The three machines are in the same windows domain Since IE that user uses to access his/her mailbox and IIS in exchange server are all kerberized, when a user tries to open the owa website, first of all, he / she will need to authenticate him / herself to the exchange webserver using kerberos. This is done by getting a ticket for the webserver from KDC. On behalf of the user, the web server will then send TGS-REQ to windows kdc to get a ticket for ldap service. The ldap service ticket is used as GSSAPI in ldap-request from exchange to AD to get information about the user mail account. Briefly, this is what happens: 1. AS-REQ from user to tgs service to get a tgt 2. AS-REP from tgs service 3. TGS-REQ from user to get a ticket for service http service of the web server 4. TGS-REP from tgs service 5. TGS-REQ from web server for service ldap to access AD 6. TGS-REP from tgs service which contains a ticket for service ldap 7. ldap request to get user account info like the mailbox location etc. The ticket for service ldap is used as GSSAPI token for ldap authentication. It's really important for me to understand how the flow of kerberos actually works for owa 2003....can anybody share his / her ideas ? thanks ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Exchange Newsletters: http://www.msexchange.org/pages/newsletter.asp Exchange FAQ: http://www.msexchange.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ Other Internet Software Marketing Sites: World of Windows Networking: http://www.windowsnetworking.com Leading Network Software Directory: http://www.serverfiles.com No.1 ISA Server Resource Site: http://www.isaserver.org Windows Security Resource Site: http://www.windowsecurity.com/ Network Security Library: http://www.secinf.net/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this MSEXchange.org Discussion List as: michael@xxxxxxxxxx To unsubscribe visit http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Report abuse to listadmin@xxxxxxxxxxxxxx ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Exchange Newsletters: http://www.msexchange.org/pages/newsletter.asp Exchange FAQ: http://www.msexchange.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ Other Internet Software Marketing Sites: World of Windows Networking: http://www.windowsnetworking.com Leading Network Software Directory: http://www.serverfiles.com No.1 ISA Server Resource Site: http://www.isaserver.org Windows Security Resource Site: http://www.windowsecurity.com/ Network Security Library: http://www.secinf.net/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this MSEXchange.org Discussion List as: dharding@xxxxxxxxxxxxxxxx To unsubscribe visit http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Report abuse to listadmin@xxxxxxxxxxxxxx ----------------------------------------- __________________________________ This message and any attachments are solely for the intended recipient and may contain confidential or privileged information.
