Users Get Multiple Login Prompts on Sharepoint 2010
-
This is my first question on the forum so feel free to move/delete/refer as necessary. What's happening is that when you access our new Sharepoint site in our head office, and your security settings are correct, you are prompted to log in once when you open the site and then you can continue on opening other pages and documents with no additional requests for credentials. Totally normal. Now, if you use an identical computer in another office in a different city (so we have the same credentials, OS, security settings), you are periodically and seemingly randomly asked to log in multiple times while browsing the site. In some cases, you will have to enter your credentials 10 times, one right after the other, before you can continue viewing a page or opening a document. It is extremely disruptive. Also, if you take that same, identical computer home or to a hotel and try to log on to our Sharepoint site, you'll have no problems. It's like you never left the office. You'll be prompted to log in once when you enter the site and then you won't see the login prompt again. The Sharepoint machines are located in our head office and the remote offices access the Sharepoint site through a VPN tunnel. The remote office can ping both the main Sharepoint site as well as the the domain controller with no problem. Has anyone even encountered this problem before? Any and all suggestions will be very welcome!

I'm not shure if you are right in this point, as it's sound that there are not the same settings. This would be the first point to check: are they really same? Are you using IE? Are the setting the same? Have you included the pages to secure pages? Do you use Kerberos?

Are you using IE? Are the setting the same? Have you included the pages to secure pages?We've actually physically moved one of the laptops from our head office to our Toronto office. Works here, works in the hotel but doesn't work in the TO office.

And no, we don't use Kerberos.

Well, that might be the answer. I have several VMs with different SharePoint installations and on some without Keberos there are Problems. Kerberos is standard nowadays, I think you are using it in AD so you might should activate it in SharePoint.

I've noticed that too. Sometimes you tell the browser (IE) to remember the credentials, and the browser asks you for the credentials again.

We've reconfigured to use Kerberos and we've noticed no change.
Sorry, then I don't have any further idea as this problem never occured by any of our customers or our own sharepoint.

Well another try! I got some new ideas Which browser are you using and what versions. Is there an update missing? Perhaps it's because of the IE options? Are they the same? Third point to look at is the firewall? Is there an extra firewall via VPN? Are there different settings?

VPN settings I will have to look into, but I know for a fact that the IE settings and updates are the same. We've actually moved one of the managers (and her laptop) from one office to the other, and she is fine here but on the same laptop in a different office she has problems. I was even able to remote in and do some testing, it was very intermittent. She says things were fine while she was in the hotel though... And the weird thing is that it's not just the one office but all the field offices that have this problem. It has to be the firewall or VPN; we're running out of other options! I will keep you posted.

So we ended up contracting an external netowrk guy to fix something completely unrelated. In order for him to dial-in to a computer at one of our other sites to do maintanence we had to temporarily turn off the anti-virus on the router. Guess what? People could log into SharePoint with no problems while we had the anti-virus turned off. Looks like the auths where getting picked up by the anti-virus on their way back out to the client. Go figure. :doh: Anyways, we've reconfigured our antivirus and everyone is happy.

Wow! I never thought of that. There are so many errors possible at those complex systems today, it's hard to figure out everyone. :)
