In the examples below user A is physically logged in on the computer while B is not.:
- Accessing My Site. If you have a setup where you have all the My Sites on a separat web application (e.g. on a different port) and your main portal standard port 80 the "Sign in as addiferent user will" NOT work accross those two web applications. Sign in as user B (from the SharePoint Sign in ... command) and then click on My Site. Who's My Site did you get to? A or B? I guess you where hoping for B, but that is wrong.
- Editing documents will give you the same issues. Sign in as user B, find a document library where user B should not have Contribute rights to. Open a document, change it, and then do a Save As back to the same library. No errors! What!??!
Anybody else having issues with the "Sign in as different user" command?
