small slapd projects

["Kurt D. Zeilenga" <Kurt@OpenLDAP.org>]

I have a couple of small projects for those interested in
getting their feet wet.

Implement a slapd global configuration flag to enable
"bind with DN and empty password returns invalidCredentials".

Implement a slapd global configuration flag to require
authentication.  Anonymous bind would return
inappropriateAuthentication and other operations (prior
to successful authentication) would return an error.

Implement a slapd global configuration flag to require
strong authentication.

Extend above to allow simple authentication if adequate
security protections are in place.

If interested, please coordinate on this list.
