I have a strange problem trying to log in to a Sharepoint site. I'm hoping someone here might be able to help me out as I'm pretty baffled as to what might be causing this issue.
The problem - I try to log on at the logon page (entering my username/pw, then hitting enter or clicking "Log On"), the page just quickly does a postback and refreshes itself. I'm never able to get past the logon page.
I'm sure that it's not a problem on the server side because I'm able to log on from multiple other machines with no issue.
I hit this problem using Safari on a Mac, but the strange thing is that I get the same issue in multiple other browsers, and even in a VM running Windows (tried IE, Chrome, Firefox, etc). I tried clearing out my cookies, cache, etc, just to be sure, but since I'm hitting this issue in every single browser it seems unlikely that would be the culprit.
Even more strange - I have successfully logged on to this site in the past with no issue. The only thing I can think of that might have possibly changed is my IP!
I'd be super grateful for any thoughts, suggestions, etc. Thanks.
