No, you can't uninclude a class.

You'll have to do it the other way round and optionally include. In the
base server class, have a little block like
if $ldap_auth {
include ldap::auth
}
Then just make sure that this variable is set true by default and set it
explicitly to false for your ldap servers, either in their nodes or
(more logically) in the ldap server class.
You *could* do it with overrides but only If you were using a define
within your base class for part of the setup and that define took a
parameter which told it whether to include the ldap class. Trivial
example:
-----------------------------------------------------------------
define includer ( $include = true ) {
if $include {
include ldap
}
}
class base {
includer { 'setup': }
}
class child inherits base {
Includer['setup'] { include => false }
}
-----------------------------------------------------------------
I wouldn't do it that way unless there were other specific benefits to
the define, though. The variable method is simpler.
