According to chapter 5 of the admin guide, "some of the backends and of the distributed overlays do not support runtime configuration yet. In those cases, the old style slapd.conf(5) file must be used." However, there is no documentation on which backends and overlays do and don't have said support. Without grokking the code, it is a trial-and-error operation at best.
Also, there is no documentation on how to add overlay-specific directives (man pages or otherwise). Take, for example, autogroup-attrset; the olcAGattrSet directive is only described in autogroup.c, and nowhere else. This is not the only instance of missing module documentation, but it should give a general idea of where to look.
Of course, grepping the code is easy enough, but you shouldn't have to do that to learn how to achieve simple configurations. If there's going to be a fundamental paradigm shift from slapd.conf to cn=config, there has to be documentation (man pages, admin guide sections, et. al.) on the appropriate methods for achieving what once was done through slapd.conf. IMHO, that should include concrete examples, such as the following, pulled from the Courier documentation:
The following LDIF could be used to add [the auditlog] overlay to cn=config (adjust to suit):
dn: olcOverlay=auditlog,olcDatabase={1}hdb,cn=config changetype: add objectClass: olcOverlayConfig objectClass: olcAuditLogConfig olcOverlay: auditlog olcAuditlogFile: /tmp/auditlog.ldif
