java - Getting Internal Attributes of LDAP Object -

i trying fetch ldap user internal attributes, couldn't find how fetch them

dircontext ctx = this.getdircontext(); list<employee> list = new arraylist<employee>(); namingenumeration<searchresult> results = null; try {   searchcontrols controls = new searchcontrols();   controls.setsearchscope(searchcontrols.subtree_scope);   results = ctx.search("", "(objectclass=person)", controls);   while (results.hasmore()) {     searchresult searchresult = results.next();     attributes attributes = searchresult.getattributes();     string fullname = this.getvalue(attributes.get("cn"));     //so on... } // on 

from ldap, want fetch each employee/person internal attributes too. default, it's not returning internal attributes [ex: createtimestamp]

you won't operational attributes unless ask them. @ present aren't asking attributes, equivalent constructing searchcontrols, or calling searchcontrols.setreturningattributes(string[]) afterwards, using argument new string[]{"*"}:this gives non-operational attributes.

to operational attributes well, use argument new string[]{"*","+"}.
