Excluding FBA users from people search

Question

I've got a mixed environment with both AD users as well as FBA users. The FBA users are stored in a seperate ASP.NET membership database.

Now when I use search, both AD and FBA users show up. I'd like to limit those results to always only show AD users, the FBA users should be entirely excluded from search. Is there a way to tell the search engine not to index these folks?

I'm not importing any of the FBA users in profile import, since there is no import for non-AD users (as far as I know). Also, setting up crawl rules won't work because they only go for URL's and I have no clue what I would have to enter there to get it to ignore FBA users.

I did try limiting the people scope by adding an exclusion. But that requires a metadata property to check and I have no suitable property to use. The AccountName property contains the claims prefix (i:0#.w or i:0#.f) to indicate forms or Windows, but the scope rules only allow for an equals check, not for a contains or anykind of wildcard characters I believe?

Answer 1

One way you could accomplish this is with the Crawl Rules on your Search Service Application in Central Admin. Look at the search results to see how the URL of the FBA users are displayed and then look at the URL of a normal domain user. Create a rule that will filter out the FBA URLs.

You can use wildcards and such to make it work. If you want to post the two URLs, we can help come up with the rule for you.

Be sure to select the "Excluded complex URLs" option when you create the rule.

In 2010 if you are using FBA with Claims you should be able to create a rule using the User Profile Property SPS-ClaimProviderType.
