Searching for all immediate children for restricted return values

Steps

To search for all immediate children of restricted return values, run the ldapsearch tool.

The special attribute "+" returns all operational attributes.

Example:

In this sample, the immediate children are ou=People,dc=example,dc=com, and the restricted returned values are sn and givenName.
```
$ bin/ldapsearch --baseDN ou=People,dc=example,dc=com \
  --searchScope one '(objectclass=*)' sn givenName "+"
```
