Hi,
I'm developing a Custom Claims Provider to resolve against the SharePoint User Profile Service since we have a large forest of upstream opco Active Directories and I don't want user searches to go back out to source. I've disabled the AD provider.
It seems to be working for the most part; as I start to search for people either from the "Share" button - or within a Person/Group field of a list item add/edit form, results are being returned to the people picker from my provider. I can select the name and all appears to resolve correctly.
If I'm sharing (as in adding a user to a group for edit / full control etc) - everything works perfectly .... however, when I add a custom list which has a person/group field in it, and try to save/commit the record, I see an error underneath the field saying"Input string was not in a correct format"
I've gone through debug but can't see anything obvious within the properties that I might have mis-set / forgotten to assign. Can anybody advise where I might need to look please?
Regards,
Steve
