Most people in my office use Mac's for their daily work. This includes using Safari for web browsing.
Unfortunately we also use a Sharepoint 2007 site for various things. Our site requires authentication against AD to view it.
Since upgrading to Mavericks everyone has been experiencing problems browsing to the sharepoint site.
The interesting thing is that not everyone has problems at the same time.
I have been able to find a fix for our issue. Figured I would post it here cause it may help some others who are having this issue.
Our issue appears to be related to having one or more SMB volumes mounted in Finder. I initially thought it was only when we had a SMB share mounted that uses the same AD auth as sharepoint, however I have since discovered that it also occurs when I have a share mounted as a guest user from a completely different domain to our sharepoint site.
If I try to load our sharepoint site, Safari starts loading the page and just sits there. It doesn't show any errors just shows the location bar with the blue loading indicator a little way in. The quick fix is to unmount any SMB shares you have mounted by clicking the eject icon next to the share in Finder. As soon as these shares are unmounted, the sharepoint page will display instantly, or you will get an access denied message. If I get the access denied message all I have to do is refresh the page and it loads instantly.
I am wondering if Safari is attempting to re-use SMB credentials or tickets used by Finder which may be causing this issue. Interesting thing is that the SMB volume still functions as normal so it is unlikely to be stale auth credentials or a stale share. Additionally if you connect to a SMB share and then load sharepoint within a short timeframe this issue does not occur. I have not determined what length of time needs to pass before this issue occurs.
