certutil-bin: certificate is valid

I'm not sure if I did this right:

../shared/bin/ldapsearch -Z -P slapd-server- -b "" -s base
"(objectclass=*)" -v
ldapsearch: started Fri Jun  2 22:23:18 2006

ldap_init( localhost, 389 )
ldaptool_getcertpath -- slapd-server-
ldaptool_getkeypath -- slapd-server-
ldaptool_getmodpath -- (null)
SSL initialization failed: error -8174 (security library: bad database.)

also...

../shared/bin/ldapsearch -P slapd-server- -b "" -s base "(objectclass=*)" -v
ldapsearch: started Fri Jun  2 22:23:41 2006

ldap_init( localhost, 389 )
ldaptool_getcertpath -- slapd-server-
ldaptool_getkeypath -- slapd-server-
ldaptool_getmodpath -- (null)
SSL initialization failed: error -8174 (security library: bad database.)
