when i run slapd -d -1 i get the folowing error.

.......
.........
loaded module back_bdb
bdb_back_initialize: initialize BDB backend
bdb_back_initialize: Sleepycat Software: Berkeley DB 4.2.52: (December  3, 2003)
module back_bdb: null module registered
line 33 (sizelimit 500)
line 37 (tool-threads 1)
line 42 (overlay        dynlist)
overlay "dynlist" not found
/etc/ldap/slapd.conf: line 42: <overlay> handler exited with 1!
slapd destroy: freeing system resources.
slapd stopped.
connections_destroy: nothing to destroy.

i've tried searching in the internet and the lists but 've found nothing.
if i remove the lines :

overlay dynlist
dynlist-attrset groupOfURLs memberURL

slapd runs ok, but without dynlist of course.
dynlist.la and dynlist.so are in  /usr/lib/ldap
thank's in advance.
