How to Modify multivalued attribute in LDAP using java API?

[Simpson Kumar]

when I modified the multivalues attribute (ex: objectclass), it get override the existing values with new values, which is a bad approach. I want to either remove or add each value by value depending upon the UI request. I don't want to override all values at a time.

say for ex in LDAP, if objectclass already contans "top","person","organizationalPerson", Now from UI request, I want to change the objectclass by removing "organizationalPerson" and adding "inetOrgPerson". I can do by collecting new multivalues from UI and override (update) objectclass but I dont want to do in that scenario, rather doing like that I need to remove ""organizationalPerson" value and add new "inetOrgPerson". How can we do from sun API? .

Here is the code that I'm following

  Attributes attrs = new BasicAttributes();
      BasicAttribute ocattr = new BasicAttribute("objectclass");
      ocattr.add("top");
      ocattr.add("person");
      ocattr.add("inetOrgPerson");
      attrs.put(ocattr);
      attrs.put("cn", "Some Person");
      attrs.put("sn", "Person");
      return attrs;
 
 
context.modifyAttributes("uid=skk27,ou=people",
                             DirContext.REPLACE_ATTRIBUTE,
                             attrs);
  

Is there any other approach to do ? could some one help on this

I have done this job.. the following API I used to remove and add multivalues attribute one by one value.

 
ModificationItem[] mods = new ModificationItem[3];

// Replace the "mail" attribute with a new value
mods[0] = new ModificationItem(DirContext.REPLACE_ATTRIBUTE,
    new BasicAttribute("mail", "[e-mail]"));

// Add an additional value to "telephonenumber"
mods[1] = new ModificationItem(DirContext.ADD_ATTRIBUTE,
    new BasicAttribute("telephonenumber", "[phone]"));

// Remove the "jpegphoto" attribute
mods[2] = new ModificationItem(DirContext.REMOVE_ATTRIBUTE,
    new BasicAttribute("jpegphoto"));
