LDAP auth - not displayed registered users in web admin

I tried ejabberd 2.1.2 against my small slapd server (only two accounts registered). In all the WebAdmin pages it shows the correct information about number of users, and their usernames.

You can try like I did, and compare the log result. Maybe it gives you some idea. I know almost nothing of LDAP.

First increase the loglevel in ejabberd.cfg to 5.

Then browse some WebAdmin, for example the statistics about the ldap host. In my case I have two vhosts, one called "localhost" with internal auth, and "ldap.localhost" with ldap auth.
http://localhost:5280/admin/server/ldap.localhost/stats/

Then check ejabberd.log It should have something more or less like:
