Note that many aspects of the "big picture" don't really relate at all to 
OpenLDAP ... and there isn't really any projects on documenting the big 
picture. Many existing documents are very outdated (to the point of being 
more effort to follow than they are worth). I have written some[1] in the 
past, but they are also out-of-date ...

Lets not get ahead of ourselves yet.

Complete examples of what? Do they only cover the use of OpenLDAP, or other 
software as well (nss_ldap, pam_ldap, samba, sudo, apache, jabber, bind - to 
list just a few of the pieces of software I have configured to use LDAP in 
some way)? The "other software" bit is really off-topic for this list (and 
the official documentation).

http://www.openldap.org/doc/admin/quickstart.html ?

That takes you about as far as it can without going off-topic.

So, you're saying non-gurus should write (or at least contribute) to 
documentation? Are you volunteering?

These examples (mail/user_logon) would be very dependant on:
-the MTA and/or IMAP/POP3/other mail protocol server being used
-the application service the user_logon service (ie pam_ldap)

The OpenLDAP developers shouldn't need to write other people's documentation. 
BTW, you may want to take up these issues on a better forum, such as the 
ldap-interop list.

I think it needs to be a combination, since some people need to give the 
guidance on what they found difficult to follow, and others would need to 
contribute documentation on that aspect.

No-one said it was. If you have only been reading RFCs, you haven't been 
judging the existing documentation fairly.

I think the OpenLDAP documentation supplied by the OpenLDAP project is 
sufficient for helping people deploy OpenLDAP.

However, moving all authentication services to use your LDAP server has 
nothing to do with the OpenLDAP project (as any LDAP server could be used).

"openldap"? Or, deploying an LDAP service and integrating services to use it?

There are means to contribute to the documentation.
