SharePoint Server 2010 with one way trusted domain -no search results for users from Trusted domain
I have a client with a SharePoint server 2010 environment. We have a local domain set up in the environment that hosts the Site. So we have domain1.local and then a one way trust was set up between the Clients internal domain and the local domain. So we have domain2.com. The access and users in SharePoint groups are all working as expected from both domains.
The problem found is the users from domain2.com are getting no results when searching while the users with the same SharePoint permissions assigned from domain1.local do see results when searching.
The only fix that seems to be suggested (that I have found) is to:
1. Change the Web App authentication from Classic-mode to Claims-mode.
2. Change the authentication on the SSA from Classic-mode to Claims-mode.
I am not comfortable with #1 since there are other application installed and configured to work with SharePoint that I am unsure if there will be a negative affect with. This environment if fully validated for FDA submissions and the applications have had Test scripts written and run. Changing the Authentication would most likely cause a whole new script having to be run on these apps.
So this leaves me with option #2 which I am trying to understand how this will work.
Will it have negative affects on the Security of the sharepoint configuration ? I am thinking not since it is just the Search ???
One article states "you will have to follow up with changing the web app over to claims-mode also". Is this true ?
Also stated is the "Search Alerts will be broken" - I dont think I have ever set up alerts on the Search - can you give me an example ?
Finally are there any other options that you know of that could help to get this working.
Am I missing something ? Is it really this involved ?
Any information would be appreciated - the security of the info on this site is very important that is why it was set up as a one way trust to begin with.
