I recently had an issue while trying to configure the authentication provider for a SharePoint 2007 site. Regardless of the authentication provider that I selected, clicking the save button would result in the following error: An object of the type Microsoft.SharePoint.Admini... named "Provisioning 1aa06c49-f543-41c2-b3f6-ce7... already exists under the parent Microsoft.SharePoint.Admini... named "". Rename your object or delete...
