Hi all, I'm facing very strange issue with enterprise vault to exchange 2003. Whenever users try to connect their mailbox using OWA they keep on getting authentication pop-up for every task they perform. If EVOWA extensions are removed from exchange servers then everything works normal. Have also tried recreating virtual directories in IIS. Not sure what goes wrong. I believe EV uses IWA authentication for users.. EV should not ask more den 2 times (max.) prompt for authenticating and retrieving their archives.idealy it asks firsts time while accessing , there after it should not. but in our era it keeps on annoying. Any help!!! Cheers vaibhav

Hi Everyone, This issue is related to Kerberos Authentication and Enterprise Vault use the Microsoft Authentication module. So Kindly check the same from Microsoft End. Abhishek

Hmmm I've seen this before and it ended up being that on the EV servers the EV install directory was locked down. Adding Authenticated Users to the directory and the webapp directory resolved it

Does this issue occurs while trying to connect to OWA from the LAN and from the internet?

Hello Vaibhav,

did you used the owauser.swf script for configuration of the EV directory

also you can check the FQDN name users are using to connect the OWA

Hi JW

Have tried this long back but no resolution came up.

I forgot to highlight that There are three Back End Servers . And amongst these three issue persist only on One of them. However if EV Extnesions are removed everything works perfect.

We tried moving mailboxes from this affected server to another one issue gets resolved... But we ca not move every mail boxes from there to another one. Microsoft also denied to accept the fact that there is authentication issue which does not works properly when there is interception of EV.

Enterprise Vault Ver: 8.3

OS: Win2k3 ENTSP2

ExchVer: 2k3 ENT

Cheers

Any chance of getting a fiddler trace from a client machine to repro the issue? You should see in the logs what file is causing the authentication request This is how we found it was an issue on our EV servers and not the OWA servers but it should help a lot http://www.fiddler2.com/fiddler2/version.asp

Vaibhav, it might be an idea to run through the steps you performed when installing and "fixing"... so others can try to spot where you might need to go to next.
