I have to admit I didn't try to compile, I just looked at the code.
However, backends are linked in as archives or dynamic libraries.
With the former, the linker - or ar? Don't remember - will happily
pick the first occurrence of the symbol after it is referenced, and
ignore the next. With the latter, I think most OSes will allow both
to be used at once - and each library will use its own version.

In OpenLDAP 2.3, './configure --enable-backends' enables all backends
except the ones you explicitly disable.

Well, personally I haven't looked closely at the code yet, and won't for
I wonder if one could write a worker which turns the requests right back
to LDAP requests and feeds them back to slapd - and then run a big part
of the current test suite against back-sock:-) Might be easier if
back-sock has an option to talk ASN.1 instead of a text protocol with
