SharePoint 2010 Claims Based Authentication - anonymous site is prompting for CBA auth when opening

Posted By:      Posted Date: September 10, 2010    Points: 0   Category :SharePoint
Hi, I have CBA setup successfully on my sites.  One site is setup for anonymous access and I have disabled "client integration" on that web application. I have a list of MS Office documents on a wiki.  When I click on one I am asked to either save or open or cancel.  Saving works fine but when I choose open, it launches the associated MS Office app.  I am then prompted for a login from CBA.  I can click cancel and the logon screen appears again.  After clicking cancel the 2nd time the document appears in the MS Office app, Word in this case. My question is how do I prevent my users from being prompted for a CBA login when clicking on these files and opening them in the native app on their machine?      --TR

SharePoint 2010 Claims Based Authenticaton site working but search is broken

Hi, I have SP 2010 sucessfully installed on a Windows 2008 R2 server with SQL Server 2008 R2.  I created local machine accounts for the following: MACHINE\mssqlservice MACHINE\sp_admin MACHINE\sp_search MACHINE\sp_farms I have setup 2 sites with public facing internet access as well as local sites. I have CBA working properly on both sites from both public and private access. My problem is that when I go to search, I am constantly redirected to an error page.

Cannot Login with Forms Based Authentication to SharePoint 2010 - Issue with the SecurityTokenServic

Please be advised I have followed the steps on http://donalconlon.wordpress.com/2010/02/23/configuring-forms-base-authentication-for-sharepoint-2010-using-iis7/. I have tried to fix the following issue for a week using different farms and SharePoint 2010 installations, however I am getting the following error when trying to authenticate using Forms Based into a Claims site: Cannot get Membership Provider with name FBARoleProvider The membership provider for this process was not properly configured. You must configure the membership provider in the .config file for every SharePoint process. 1. I am certain the membership provider is configured in the SecurityTokenServiceApplication webservice as I can manage users and roles in IIS7 using the SecurityTokenServiceApplication website. 2. I am certain that membership provider is configured in the both the Claims Web Application and Central Admin as I can manage users and roles in IIS7 using their websites. 3. I know the issue is the SecurityTokenServiceApplication service as I had to set <serviceDebug includeExceptionDetailInFaults="true" /> to get the error above. 4. I can log into the Claims Based Application using windows authentication, however I am unable to see the users on the people picker despite that I can see them from the application's site on IIS

Changed to claims based authentication, now I can't access my site. Please help! Time is of the ess

I am in a pretty big bind. I have a sharepoint 2010 site, that was using classic windows authentication. It worked fine from the inside, and I was able to extend it to the outside and it was using https with an SSL certificate. However, my performancepoint reports and my external lists weren't working when the site was accessed from the outside. Apparently this is a known issue with using classic authentication on the outside, so I tried to switch over to claims based authentication. I followed this guide: http://blogs.technet.com/b/wbaer/ar...point-2010.aspx I obviously changed the contoso stuff to my domain name, and changed all of the config files. The problem is, now I can't access the site at all from the inside or the outside. Here is the error I get in my logs: code: An exception occurred when trying to issue security token: Could not connect to [url]http://localhost:32843/SecurityTokenServiceApplication/securitytoken.svc/actas.[/url] TCP error code 10061: No connection could be made because the target machine actively refused it . My Sharepoint Central Administration site gives me this warning: code: The Security Token Service is not issuing tokens. The service could be malfunctioning or in a bad state. Remedy Administrator should try to restart the Security Token Service on the boxes where it is not issuing tokens. If problem persists, f

Forms Based Authentication in SharePoint 2010



I'm trying to figure out how to setup FBA in SharePoint 2010.  I know that FBA is now just a subset of Claims Based Authentication, but I'm confused by some of the different approaches that I've seen on some technet blogs:



Having seen the two, one doesn't setup a SQL while one does.  Both are vague in the user account that is used to manage the FBA users.  I'd like to get some clarification if that's possible.  Thanks in advance!

Problem with Sharepoint 2010 - Claims Auth - Windows Auth and FBA. consistent redirects back to "cho


We have sharepoint 2010 foundation site that we can successfully login with via IE, Firefox, Chrome both on the domain and externally with Claims Authentication with only Windows Auth type selected (NTLM).

Once we add FBA and use the default signin page, we can still login (we select Windows Auth from the dropdown) BUT it only works on the domain. When we try to access externally, the only browser that works is FireFox. Both Chrome and IE just constantly redirect back to the Choose Authentication dropdown screen.

We have tried for the last 2 days to sort this out. Has anyone else experience this? It looks like the default sign in page somehow doesn't set the cookie for IE and Chrome and just bounces us back to the sign in page...

Thanks for any info...

To clarify, we are not even using the FBA yet. We are trying to login only with the windows auth and domain accounts...

Opening Word 2003 document from sharepoint site in word 2010.


When using sharepoint services with word 2003 on an XP machine, everything works fine. We bought some new computers where we now have windows 7 and office 2007/2010. These work perfect too. Even the 64-bit computers.

We are very happy with the new office version, so we decided to upgrade the entire company. As a test, we upgraded 1 PC. But this is not working. So we upgraded office, later we reinstalled it. But nothing helps. This is the problem: I surf to the document click it to open it, and then Word hangs. "contacting server". This is not always the case, sometimes it works, sometimes it doesn't. This even with the same document.

We would really like to upgrade to office 2010 entirely. But we're not going to buy licences we cannot use. Anybody got a solution?
