getent passwd doesn't show ldap user

[stefano malini <lozingalo@gmail.com>]

hi,
as said before i reinstalled openldap and configured nslcd.conf and 
nsswitch.conf.
at the moment geten passwd doesn't show ldap user.
as follow you see that i create a user nslcd_proc for nslcd lookups.
this user belong to the System organizationalUnit.
follow nslcd.conf and slapd.conf (please take a look of ACLs for 
nslcd_proc):

------------------------------------------------------------------
# /etc/nslcd.conf
# nslcd configuration file. See nslcd.conf(5)
# for details.

# The user and group nslcd should run as.
uid nslcd
gid nslcd

# The location at which the LDAP server(s) should be reachable.
uri ldap://localhost:389

# The search base that will be used for all queries.
base dc=amahoro,dc=bi

# The LDAP protocol version to use.
#ldap_version 3

# The DN to bind with for normal lookups.
binddn uid=nslcd_proc,ou=System,dc=amahoro,dc=bi
bindpw *****

# The DN used for password modifications by root.
#rootpwmoddn cn=admin,dc=example,dc=com

# SSL options
#ssl off
#tls_reqcert never

# The search scope.
#scope sub

------------------------------------------------------------------

slapd.conf ACLs:
access to attrs=userPassword
        by anonymous auth
        by self write
        by * none

access to *
        by dn.base="uid=nslcd_proc,ou=System,dc=amahoro,dc=bi" read
        by self write
        by * none

thanks
