At Novells Brainshare Conference, I heard a couple of the companys developers touting LDAPzone.com, a handy Web site for keeping track of what is happening with LDAP, from a (theoretically) vendor-neutral viewpoint.
The site has useful information about implementing directories on a variety of operating system platforms, lots of tips and tricks, white papers, and a fairly active discussion list. One of the stated goals of the site is to host a community effort that supports and improves tools and techniques for the LDAP environment. Anyone interested in contributing to the effort should take a few moments to visit the site at www.ldapzone.com.
But dont think that the site is entirely vendor-neutral. One of the most glaring indications of this is that Novell is the only sponsor of the site and that Novell announcements are prominent throughout the site.
