I have a trusted identity provider which is associated with a claims provider.
ClaimProviderName is set to match the custom claims provider.
This appears to be sufficient to give the expected search results when using the claims picker under e.g.
site -> People and Groups -> Site Members as follows:
However, if I access the people picker under Central Administration (e.g. when managing administrators for a Secure Store target application), I get a different picker, which includes both of the expected results, but additionally shows spurious results for whatever happens to be typed in under the trusted identity provider:
These entries are correct:
However, this entry is incorrect - there is no "vogon" user, and the trusted identity provider shouldn't even be showing results directly, since it is associated with a claims provider:
How do I get the People Picker in Central Admin to honor the ClaimsProvider association for a trusted identity provider?
