Update the information active directory data using the java JNDI ?

Question

I want to use the java JNDI to update/insert the user information which available or not-available in the Active directory. I have created an application which allow Active Directory user to get their information and I am able to extract the data from the active directory but I don't have any idea how to save the data in active directory using jndi Java which user want to update.

Answer 1

ctx.modifyAttributes(unique_name,iteam); 

using this method you can update the record in the active directory. name is the denoting the combination of searchbase and search filter which make the data unique in ldap active directory.

ModificationItem[] iteam = new ModificationItem[number_of_attribute_you_want_to_update];

iteam is the array of changes which you are going to do.

Attribute name = new BasicAttribute("displayName",userDetail.getName());
// replacing the value
    item[0] = new ModificationItem(DirContext.REPLACE_ATTRIBUTE, name);

setting the value
