Problem with password changing with passwd command

[luiz@pucrs.br]

Hello

I´m installing a OpenLDAP for user authentication here. The server is the
version 2.1.21, running in a Solaris 9 box and I´m testing a Linux Red Hat
9 client. I can log in normally.
When I try to change password, the procedure seems to be normal, that is,
the password entry is really changed in LDAP base in server (I can see it
with slapcat command). The problem is that the new password is anything
unknown, because I can´t login again neither whith new password nor with
the old password.
My slapd.conf:
