GlassFish + JNDI + LDAP + JAVA

STEP 1: Create JNDI LDAP Resource

In the GlassFish admin console create a JNDI Custom Resource with the following parameters:

1. Give it a JNDI name such as myLDAP
2. Resource Type:
3. Factory Class: com.sun.jndi.ldap.LdapCtxFactory

Add the following as additional parameters:

1. Name: Value: the reader dn

2. Value: the password

3. Name: URL Value: ldap://servername/baseDN

STEP 2: JAVA code to access the LDAP

Use code similar to the following to access the LDAP:

try {
Context initCtx = new InitialContext();
DirContext ctx = (DirContext) initCtx.lookup("myLDAP");

SearchControls ctls = new SearchControls();

String searchfilter = "(mail="+ email +")";
NamingEnumeration answer ="", searchfilter, ctls);

SearchResult entry = (SearchResult);
Attributes attrs = entry.getAttributes();

} else {
success = false;
} catch (NamingException e) {

Thanks, Sud.
I want ask one question.
If i want to use Windows Active Directory User-Password for Login in client application (of Glassfish server application), How to use it?

I think, Windows AD <=> LDAP <=> JNDI <=> My app. But what will be the look up key?

Will you be able to give other information??

This is my email :

Seems like com.sun.jndi.ldap.LdapCtxFactory is not picking up the authentication properties and I keep getting javax.naming.NoPermissionException. Any idea what properties to use to force LdapCtxFactory to authenticate?

tom said...

Did anyone find a solution to the question which properties to use to force LdapCtxFactory to authenticate?? Kind Regards, Thomas

I have the same problem with authentication against AD.
I posted the problem here:

Are there any solutions?

Hello would you mind stating which blog platform you're using? I'm planning to
start my own blog soon but I'm having a hard time deciding between BlogEngine/Wordpress/B2evolution and Drupal. The reason I ask is because your layout seems different then most blogs and I'm looking for something completely unique.
P.S Sorry for getting off-topic but I had to ask!

Today, I went to the beach with my children.
I found a sea shell and gave it to my 4 year old daughter and said "You can hear the ocean if you put this to your ear." She
put the shell to her ear and screamed. There was a hermit crab inside and it pinched her ear.
She never wants to go back! LoL I know this is completely off
topic but I had to tell someone!
