[SURESHKUMAR <sureshkumar@siptech.co.in>]

Hi,

    When I run the LDAP Server it is running fine.I confirmed it first 
using ps -A.To confirm it again I tried searching using the following 
command : ldapsearch -x -b '' -s base '(objectclass=*)' namingContexts
but I get the following error : ldap_bind: Can't contact LDAP server.

My system set up is :
OS - RedHatLinux 7.3
DB - BerkeleyDB

Iam attaching my slapd.conf file,can anyone help me .

# Sample security restrictions
#
#   Disallow clear text exchange of passwords
# disallow bind_simple_unprotected
#
#	Require integrity protection (prevent hijacking)
#	Require 112-bit (3DES or better) encryption for updates
#	Require 63-bit encryption for simple bind
# security ssf=1 update_ssf=112 simple_bind=64

# Sample access control policy:
#	Root DSE: allow anyone to read it
#	Subschema (sub)entry DSE: allow anyone to read it
#	Other DSEs:
#		Allow self write access
#		Allow authenticated users read access
#		Allow anonymous users to authenticate
#	Directives needed to implement policy:
# access to dn.base="" by * read
# access to dn.base="cn=Subschema" by * read
# access to *
#	by self write
#	by users read
#	by anonymous auth
#
# if no access controls are present, the default policy is:
#	Allow read by all
#
# rootdn can always write!
