I have install openldap on CentOS and configuration is as follows

Server ( CentOS)

Openldap-2.3.43
IP 192.168.0.10
netmask 255.255.255.0
user name for ldap is ldapuser
In ldap.conf
URI ldap://192.168.0.10/
BASE dc=example,dc=com
TLS_CACERTDIR /etc/openldap/cacerts (Created Certificate on Server)

after testing LDAP data base using
#ldapsearch -x -b 'dc=example,dc=com' '(obljectclass=*)'

O/p was working fine but now its giving me error as follows

ldap_bind: Can't contact LDAP server (-1)



2. Client (Ubuntu)
IP 192.168.0.20
netmask 255.255.255.0

conf file at /etc/ldap/ldap.conf
HOST 192.168.0.10
BASE dc=example,dc=com
TLS_REQCERT allow
TLS_CACERTDIR /etc/ss
l/certs


Note: both OS (Server and Client) are different unix flavor

Same error getting on client (Ubuntu)
Please help me to resolve this issue.

If u need and more info then pls let me know

sounds like a network issue. or slapd isn't running.

Or the firewall is blocking the ldap port, try disabling the firewall to see if it's the one causing the problem

RMI
