Question

Problem updating ADAM Schema using a Java program

Asked by: bganoush

Hi,

My name is Nick and my friend bganoush has been nice enough to let me use his account to ask for some help in here.

Some background info first. I have access to a windows 2003 server where ADAM (active directory application mode) is installed. I installed a new ADAM instance on this server and created an application partition called o=JNDITutorial. This ADAM instance is setup to run as a network service and the administrator for this instance is my account on the server itself. Inside this application partition I also created an organizational unit ou=LDAPUsers. I then added a user to this ou, CN=Nick,OU=LDAPUsers,O=JNDITutorial and enabled the account and set a valid password. From there I added this ADAM user to the Administrator group/role that is already defined in the ADAM schema. I'm thinking this user Nick should now have full administrative rights within the ADAM instance.

What I want to do know is extend the ADAM schema so that I can store Java objects in the directory.
I've been reading this tutorial http://java.sun.com/products/jndi/tutorial/trailmap.html
In the preparations section is a Java program that will connect to the LDAP server and create the necessary schema classes so that the directory can store Java objects. The program can be found here
http://java.sun.com/products/jndi/tutorial/config/LDAP/CreateJavaSchema.java
The attributes and classes I am trying to add so that the directory supports Java objects can be found here, http://java.sun.com/products/jndi/tutorial/config/LDAP/java.schema

I modified the program by hardcoding my server url in along with the username and password for the user CN=Nick,OU=LDAPUsers,O=JNDITutorial.
The program connects to the ADAM server perfectly but then fails when it tries to update the schema. Here is the exception that is thrown,

[updating Active Directory schema ...]
[locating the schema]
[inserting new attribute definitions ...]
javax.naming.NoPermissionException: [LDAP: error code 50 - 00000005: SecErr: DSID-031520D9, problem 4003 (INSUFF_ACCESS_RIGHTS), data 0

at CreateJavaSchema.updateSchema(CreateJavaSchema.java:211)
at CreateJavaSchema.run(CreateJavaSchema.java:109)
at CreateJavaSchema.main(CreateJavaSchema.java:97)

The exception is thrown when it tries to create the very first attribute. I think it's telling me the user I supplied doesn't have sufficient rights to modify the schema. I thought this would work given that the user I created has been added to the Administrators role/group within the ADAM instance.

I am a seasoned Java developer but this is my first stab at LDAP and using ADAM. I am rather disappointed with the lack of documentation out there on ADAM. Most of it gives the basics and assumes you have worked with Active Directory before. So finding help on how to update the Schema using this Java program has been frustrating.

I appreciate any help anyone can provide,

Thanks,
Nick

This seems tobe the case. Can you modify the schema with this user outside Java? What happens if you connect to LDAP via any other mean and try to modify the schema?

The only tool I have found that allows me to edit the ADAM schema is ADAM-schmmgmt.dll and it is a tool provided by Microsoft. It snaps into the MMC (microsoft management console). To use this tool, I give it a server to connect to as well as a username and password. The username and password belong to a Windows user that I designated as the admin to the ADAM instance when I initially installed the ADAM instance. These sets of tools are provided with the ADAM installation.

Do you know of any other tools for managing an ADAM instance or modifying it's schema?

Is it even possible to create an ADAM user that would have the rights to modify the schema through a 3rd party tool like the small Java util I am trying to use?

I'll see if I can re-designate the category of this question. It has definetly moved from a programming question into an Active Directory/LDAP question.

Sorry I am not aware of any tools. But I think if you manage to connect with a user outside Java it will give you an insight into what's going on.

I managed to figure out what was going wrong.
First read this:http://support.microsoft.com/kb/838342

Basically you have to create a user in the configuration partition and assign them to the administrator group for the configuration partition. You will now have an ADAM user that can update the ADAM schema instead of having to use a Windows user account.

My previous admin user was defined in the application partition which had insufficient rights to update the Schema like I wanted.

From here it was a simple matter of giving the program this new admin user DN along with the password. The Java schema updates were applied nicely and I am now finally on my way.

Thanks for all the help girionis.
