Internet/iNotes Idle Session Timeout

Why wont my iNotes users lock out after 60mins of idle-ness? My Settings:

Server config doc, under the internet prot tab, DWA tab, in the “Idle Session Timeout” = 60mins

Session Authentication = Single Server

If I look in the Admin client I can see the user name. I can see that the user is scheduled to expire at a specific time. And if the user session is idle past that period of time they still are able to access mail without getting a login prompt

What else affects this, or is it just broke?

Subject: It was working in 6.5.6FP2 Server

just to let you know why i posted in this forum - this feature was working great in 6.5.6 - after upgrade it seems to have stopped working - despite the admin tool showing when expriation will occur (so it is calculated, just apparently not enforced)

Subject: Session Timeout

I retested session timeouts in the lab and found it to work properly. The only thing I can suggest at this time is to check the date and time on the client system to make sure it’s the same as the server.
