How to add an self defined attribute to ldap user?

Question

Hi, I have created an attribute in LDAP using the following code.

attrs.put("NUMERICOID", "1.3.6.1.4.1.42.2.27.4.2.3.1.1.9");
            attrs.put("NAME", "myattribute");
            attrs.put("DESC", "for JNDITutorial example only");
            attrs.put("SYNTAX", "1.3.6.1.4.1.1466.115.121.1.15");
            DirContext schema = context.getSchema("");
           DirContext newAttr = schema.createSubcontext  ("AttributeDefinition/myattribute1", attrs);   

The attribute is created successfully, Now I am trying to add this attribute to a user say "user1"(uid).

Attributes attributeslist = context.getAttributes(ld.getUserDN(username));
            attributeslist.put("myattribute1", "");
            context.modifyAttributes(ld.getUserDN("test5"), DirContext.REPLACE_ATTRIBUTE, attributeslist);

But it gives me object class violation error.

Can anyone help me to solve this? I need to add an user defined attribut to the user using java code.

Answer 1

You create the attribute, then you choose a class to which it should belong, and update the class.

You could modify a base class (comes with the LDAP servers base schema), an effective class (a class of object that can exist on its own, like inetOrgPerson), or an auxiliary class (cannot make an object of this type by itself, but it extends another object class).

So define an aux class to 'hold' your new attribute, then add an entry to the Object Class of your target object, with the name of your class, and then you can add the attribute to the user.

We do this all the time.
