SharePoint Custom Claims Provider on CodePlex

If you have a basic requirement to implement a Custom Claims Provider in your SharePoint 2010 or SharePoint 2013 environment to integrate with either your Active Directory or LDAP repository, you no longer have to write a Custom Claims Provider from scratch!

CodePlex now has a project for a Custom Claims Provider that is packaged as a SharePoint Farm Solution that can be readily deployed to either your SharePoint 2010 or SharePoint 2013 Farms:
