That was my impression when I first tried it. Since the control result
is exactly like the ldap search result value, it means it can hold a lot
of things.

Does web2ldap have any special handling of the back-config entries? I
find that using a regular ldap client to handle these entries is
cumbersome (didn't try web2ldap: only lyma and gq so far).
