Unable to connect to OpenLDAP over SSL
Yasir Khan
I am using Netscape LDAP Java SDK 4.1. I am trying to connect to online
OpenLDAP server running over SSL. LDAP Browser is successfully connected to
the OpenLDAP server over SSL. But every time when I run my own code I get
the following error.
netscape.ldap.LDAPException: SSL connection to ldap.openldap.org:636 (91);
Cannot connect to the LDAP server

at LDAPConnector.connect(LDAPConnector.java:20)
Here is my source code:
LDAPConnection m_ldpCon;
System.out.println("Creating LDAPS Connection");
JSSESocketFactory obj_jsseSocketFactory = new JSSESocketFactory(null);
m_ldpCon = new LDAPConnection(obj_jsseSocketFactory);
m_ldpCon.connect("ldap.openldap.org", 636);
Plz help me to get rid of this error ...?

latest code and problem.
Source Code:
public static void main(String[] args) {
String str_ldapsHost = "ldap.openldap.org";
int i_ldapsPort = 636;
String str_baseDN = "cacertificate=New,o=ascertia.com.pk";
performLdapSearchUsingNetscape(str_ldapsHost, i_ldapsPort, str_baseDN,
true);
// performLdapSearchUsingNovell(str_ldapsHost, i_ldapsPort, str_baseDN,
true);
}
public static void performLdapSearchUsingNetscape(String a_strHost, int
a_iPort, String a_strBaseDN, boolean a_bUseSSL){
try{
netscape.ldap.LDAPConnection obj_connection = null;
if( a_bUseSSL ){
System.out.println("Adding Security Providers ...");
java.security.Security.addProvider(new
com.sun.net.ssl.internal.ssl.Provider());
System.getProperties().put("java.protocol.handler.pkgs","com.sun.net.ssl.int
ernal.www.protocol");
System.out.println("Connecting to LDAPS server
"+a_strHost+":"+a_iPort);
netscape.ldap.factory.JSSESocketFactory obj_sslSocketFactory = new
netscape.ldap.factory.JSSESocketFactory(null);
obj_connection = new
netscape.ldap.LDAPConnection(obj_sslSocketFactory);
}
else{
System.out.println("Connecting to LDAP server
"+a_strHost+":"+a_iPort);
obj_connection = new netscape.ldap.LDAPConnection();
}
obj_connection.connect( a_strHost, a_iPort );
System.out.println("Connection to LDAP server
"+a_strHost+":"+a_iPort+" is successful");
System.out.println("Perfoming LDAP search ...");
netscape.ldap.LDAPSearchResults obj_ldapResults =
obj_connection.search(a_strBaseDN, netscape.ldap.LDAPv2.SCOPE_SUB,
"objectclass=*", null, false);
System.out.println("LDAP Results Found :
"+obj_ldapResults.getCount());
}
catch (Exception ex) {
ex.printStackTrace();
}
}
Here is the output:
Adding Security Providers ...
Connecting to LDAPS server ldap.openldap.org:636
Connection to LDAP server ldap.openldap.org:636 is successful

netscape.ldap.LDAPException: The connection is not available (80); Unknown

I have also tested the same program with my local Netscape Directory Server
v4.2, but got the same results. Any help or ideas would be highly
appreciated.
Thanx.
