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!
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.
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.
Anyways, we've reconfigured our antivirus and everyone is happy.
