I have CentOS-5.4 box with all updates.I want to use samba as PDC with ldap
backend. All works fine, except winbind daemon. My samba version is 3.4.7.

# winbindd -D -d 3

# wbinfo -i test
test:*:50001:513:test:/home/W3/test:/bin/false

all fine, but in log file I get the following error

[2010/02/02 17:16:55, 3] winbindd/idmap.c:302(idmap_init_domain)
idmap backend passdb not found

Why does it try to load passdb.so? It was build statically

checking how to build idmap_passdb... static

When i try to build it dynamically

./configure \
...
--with-shared-modules=idmap_passdb \

I get the following error
