I have a very specific problem in access to LDAP.

I need to make an LDAP query, where I tell him to return all user attributes.
I do not know all their names, and changes may occur in naming them, adding new, etc.

I searched on Google and several examples in all cases you need to know the name of the attribute whose value I want to retrieve.

My question is then:
How do I make a query to LDAP using Java code and retrieve the names of all attributes and their values?
