"subordinate" was not quite a "basic" function, not more basic than 
using overlays, though.  To obtain the same behavior of glueing you need to:

<2.2>
database xxx
suffix "cn=sub,<SUFFIX>"
subordinate

database yyy
suffix "<SUFFIX>"
</2.2>

<2.3>
database xxx
suffix "cn=sub,<SUFFIX>"

database yyy
suffix "<SUFFIX>"
overlay glue
glue-sub "cn=sub,<SUFFIX>"
</2.3>

i.e. the "subordinate" in each subordinate is replaced by a "glue-sub 
<DN>"; first of all, an "overlay glue" must be used to install the glue 
overlay.

I suggest you file an entry in the FAQ after playing a bit with it.  I'm 
too biased towards its internals to do something useful that is not too 
technical.
