want show users , roles list, need change query or else in advance.

you can use org.apache.directory.ldap.client.api.ldapconnection easy search.

once bind connection, search on connection. loop through cursor object want. first parameter should match dn of users parent. below example give idea.

entrycursor cursor = connection.search( "ou=users, dc=example, dc=com", "(objectclass=*)", searchscope.onelevel, "*" );      while ( cursor.next() )     {         entry entry = cursor.get();             //play entry     }
