When my users log into Sharepoint via HTTPS using NTLM they receive a windows username and password prompt. Once successfully logged in they have access to my portal based on their access priveledges.
When a user opens any document, such as a MS Word doc, they receive a secondary prompt for authentication. The same username and password that the entered the first time is required a second time. This second prompt is an issue.
Microsoft support says that this is how the system is designed to work. With this post I am verifying MS's response.
Please note the second authentication prompt occurs when your comming over the internet and locally.
I know there is more technical information required as far as security settings in IIS and sharepoint but what I am trying to gather is if in your HTTPS site do you get a second prompt when opening sharepoint services documents via MS Office 2007?.
