I everyone,
I know this is not a support site (per say) but I want to ask a “General Question” to see if anyone else has come across a particularly vexing issue I have with a site……………………..
At random times during the day users will be forced to re-authenticate if they are already logged in or as they log in they all get the generic log in screen poppi up three times then they get a blank screen.
In my experience this has always been simple change in the browser settings & yet despite reassurances from the on-site technical team that ALL browser are configured correctly there are still many occasions where users are being prompted to login & the credentials are being rejected & the user gets a blank screen.
I’m fairly sure it’s actually a network issue within the company, or an Active Directory Issue but I am being constantly told by an increasingly irate IT Manager that it has to be SharePoint.
Has anyone else ever had this experience, is there a default timeout for authentication to AD that I don’t know about?
Any ideas of pointers would be greatly appreciated because I am all Googled out of this issue now 🙁
Tia
Don’t forget that if an unauth exception happens anywhere in code and not in elev priv it is going to ask the user for credentials. You need to check what the pages are doing, accessing any assets over the network, unpublished assets, rss feeds etc?
Is this all pages?
Is it the page which causes it or an asset the page requests? Use fiddler to track down which requests are causing the 401.
Browser settings wise, site must be in the Intranet zone to automatically pass credentials. This becomes irrelevant though if the user types them in correctly.
