that symbol is in the reentrant version of libldap, e.g. libldap_r;
it looks like the library is not in the appropriate place.  I guess
it should be installed before, or it is not actually linked
by back_bdb.la.  You should try to see if is back_bdb.la (actually,
../servers/slapd/back-bdb/.libs/back_bdb.so.2) is linking libldap_r.so
and if it doesn't you should check why (maybe something is missing
in back-bdb/Makefile.in?)

Good question.

> After all is it usefull to use modules ?

IMHO no.  I never tried, that's why I cannot really help but give
a few twopence hints on dynamic linking...
