Before we start, let me tell you that I did some RND work and have found some solutions regarding this at Microsoft site.
Get rid of "Security Alert" pop up. and also have found this.
Issue: When I log off from portal, we get this secuirty pop up stating
"You are about to be redirected to a connection that is not secured......... Yes ..No"
The main problem is, when the user log in to the production portal, he is not able to see the same error on the same machine which was used when he was testing in the Test Portal and got that error during testing.
So, if it would have been IE issue, he must be facing this log off issue from Production Portal too, which is not the case.
Can someone please guide me ?
I am totally lost..
