i am able to import this ldif file into database.
also when i perform the ldapsearch on this server with command
"ldapsearch –x –W –D “cn=manager, dc=example, dc =com” –b “dc=example, dc=com”"
i get correct output.

but when i am trying to search from another client machine, i am getting "error ldap_sasl_bind(SIMPLE): Can't contact LDAP server (-1)"

my ldap client configuration file /etc/openldap/ldap.conf is
HOST 10.48.13.141
BASE dc=example,dc=com
port 389
.

also when i configured address book on mozilla on server., it is working fine.

but not working on another machine.

is any configuration is missing on client machine.

please help.

both ldap server and client are configured on rhel4es without any firewall or selinux.

!Can't contact" suggests a network / irewall issue, or the server is not listening on that ip. does netstat -plnt on the server show it is listening?

yes, please find the output of netstat.
