Forum OpenACS Development: User search based on acs-authentication

I have a new feature developed by Michael Steigman for MGH that allows searching authentication authorities for users.

This adds a service contract definition and supporting code to allow authorities to return search results. It is already implemented for auth-ldap.

It also includes a local user account search so that the search experience is consistent for local or external authorities.

I'd like to add this to the core package. Any objections or suggestions?
