Ldap Authentication using JSP

[vinayak gagrani]

Anyone who knows how to do it, I need it urgently. 

I have been only able to verify a ldap id is present or not.

if you give links to some webpage code please do try it once, as most of the google results are not working

The page asks for subscribing but if you search via google it will show u all content (thats how i got access)

 

Code copied here if you cannot access it

I haven't compiled or checked code but with some modification it should work or at least it can provide guidelines to make something similar

@gagrani if imported library is not in java by default then install/get it

 

 

Servlet Code to authenticate the Users in LDAP:

import netscape.ldap.LDAPConnection;
import netscape.ldap.LDAPSearchResults;
import netscape.ldap.LDAPAttribute;
import netscape.ldap.LDAPAttributeSet;
import netscape.ldap.LDAPEntry;
import netscape.ldap.LDAPException;
import java.util.Vector;
public java.util.Hashtable AuthenticateUser(String strUName, String strPwd) throws LDAPException
{
LDAPConnection oLDAPConn = null;
LDAPSearchResults oLDAPSearchRes = null;
LDAPAttribute ldapAttr = null;
LDAPAttributeSet ldapAttrset = null;
LDAPEntry ldapEntry = null;
java.util.Hashtable hAttributes = new java.util.Hashtable();
try
{
oLDAPConn = new LDAPConnection();
oLDAPConn.connect(LDAP_SERVER,LDAP_SERVER_PORT);
oLDAPConn.authenticate(LDAP_DIRMANAGER,LDAP_DIRMGRPWD);
strLDAPBase = "dc=XXX";
strUser = "(uid=" +strUName+")";
oLDAPSearchRes = oLDAPConn.search(strLDAPBase,LDAPConnection.SCOPE_SUB,strUser, null, false);
if(oLDAPSearchRes != null)
{
if( oLDAPSearchRes.hasMoreElements() && oLDAPSearchRes.getCount() > 0)
{
java.util.Enumeration enum = null;
ldapEntry = oLDAPSearchRes.next();
oLDAPConn.bind(ldapEntry.getDN(),strPwd);
for(int i = 0; i < strAttributes.length; i++)
{
ldapAttr = ldapEntry.getAttribute(strAttributes[i]);
if(ldapAttr != null)
{
enum = ldapAttr.getStringValues();
String strTemp = (String)enum.nextElement();
hAttributes.put(ldapAttr.getName(),strTemp);
}
else if(ldapAttr == null)
{
hAttributes.put(strAttributes[i]," ");
}
}
enum = null;
}
}
oLDAPSearchRes = null;
ldapEntry = null;
ldapAttr = null;
}
catch (LDAPException e)
{
System.out.println("Exception occured in LDAP AuthenticateUser Method : " + e);
}
finally
{
if(oLDAPConn.isConnected())
{
oLDAPConn.disconnect();
oLDAPConn = null;
}
}
return hAttributes;
}// End of the AuthenticateUser method.

you need to give your own values for the following in the above code:

LDAP_SERVER
LDAP_SERVER_PORT,
LDAP_DIRMANAGER,
LDAP_DIRMGRPWD,
"dc=XXX"

Pravarakhya

Hope this helps :)
