-rwxr-xr-x 1 henson henson 1773576 May 21 12:54 back_bdb.so
(and no .la at all - on platforms where that's feasible)
The documentation currently says to use the .la file:
http://www.openldap.org/doc/admin24/slapdconf2.html#cn=module
Although under linux I've always just used the .so file myself. Getting rid of the .la would require a documentation update and also possibly config changes for everybody who listened to the documentation :).
