LDAP setup on LAN

I was so happy till this morning as my LDAP authentication using pam was working fine on same host, i-e server was runnning on same host and I was able to telnet ftp ssh to this host.

so I wiped out database i-e deleted all users, migrated users, shadow, and group info from a another machine on network , and populated my ldap sevre but I didn't change any stuff on server.

I setup nsswitch.con , ldap.conf , system-auth on the clietn machine, so that a user logsinto this machine, this machine will send info to ldap server and and user will be authenticated, but that was only my dream.

here are my config files.

passwd:      files ldap
shadow:      files ldap
group:       files ldap

#%PAM-1.0
# This file is auto-generated.
# User changes will be destroyed the next time authconfig is run.
auth        required      /lib/security/pam_env.so
auth        sufficient    /lib/security/pam_unix.so likeauth nullok
auth        sufficient    /lib/security/pam_ldap.so use_first_pass
auth        required      /lib/security/pam_deny.so

account required /lib/security/pam_unix.so
#account required /lib/security/pam_ldap.so

password    required      /lib/security/pam_cracklib.so retry=3 type=
password    sufficient    /lib/security/pam_unix.so nullok use_authtok md5 shadow
password    sufficient    /lib/security/pam_ldap.so use_authtok
password    required      /lib/security/pam_deny.so

session     required      /lib/security/pam_limits.so
session     required      /lib/security/pam_unix.so
session     optional      /lib/security/pam_ldap.so

All I was getting in slapd.log, on ldap server was as under and I was trying to loging as user jabbasi. while if I do search on ldap server or I directly loginto ldap server as jabbasi I get logged in whithout issues. If anyone can help me on this that why my authenticaiton fails from remote machine and works locally on ldap server.
