Domino Web Access Redirect requires two logins

I use the DWA redirect for conecting users to their web mail. However, the problem I have is that sometimes (inconsistently) after a user has requested to link to their email, they log into domino, then during the redirect, the same log in prompt appears and the user must log in again. After the second log in their web mail appears.

I thought that by specifying Single Server for Session Authentication in the config (internet protocols, dom web engine, http sessions) would remedy this problem.

Any have any input to offer?

Thanks.

Never mind - I figured it out. Had to fiddle with the parms in the redirect nsf.

Hi Gerald

May I ask you what param’s you had to update to get this to work correctly? The reason I ask is because I’ve just this wk landed a new job, and the previous admin (whom I never met) had already implemented the web mail redirect & SSO. But the redirect always prompts twice for users who are not located on the notes server where the redirect db is located. This is causing much confusion to the userbase, and any pointers on this issue would be greatly received. Dom R6 environment, running on Windows 2003 servers (FYI). Cheers
