Security Software

Dear

I have setup Directory Server 6.2 on server A and enable Samba on server B

with smb.conf :
# WORKGROUP = WORKGROUP
workgroup = wktdom
netbios name = wkt-hk11
server string = Samba Server
security = user
#security = share
hosts allow = 192.168.0. 127.
load printers = yes
log file = /var/samba/log/log.%m
max log size = 50
#passdb backend = smbpasswd
passdb backend = ldapsam:ldap://192.168.0.116:389
ldap suffix = dc=wktco,dc=com
ldap admin dn = cn=Directory Manager
os level = 64
domain master = yes
preferred master = yes
admin users = choyb
domain logons = yes
logon script = %m.bat
logon script = %U.bat
logon path = \\%L\profiles\%U
logon home = \\%L\%U\profile
logon drive = P:
wins support = yes
dns proxy = no
add user script = /usr/sbin/useradd %u
add group script = /usr/sbin/groupadd %g
add machine script = /usr/sbin/useradd -n -g machines -c Machine -d /dev/null -s /bin/false %u
delete user script = /usr/sbin/userdel %u
delete user from group script = /usr/sbin/deluser %u %g
delete group script = /usr/sbin/groupdel %g
[homes]
comment = Home Directories
browseable = yes
writable = yes
path = /export/home/smbshare
guest ok = yes

Tried bring up Samba on Server B, but keep getting error :
"failed to bind to server ldap://192.168.0.116:389 with dn="cn=Directory Manager" Error: Can't connect to the LDAP server"

Can anyone shed some light ???

Thanks very much !!
