	I find it difficult to think is a client problem, because we are having
the problem with at least three different client software (postfix
2.3.8, courier-imap 3.0.8 and freeradius 1.1.3). The errors are
provocating that users are being not found in the clients, and I know
that with our previous ldap versions there isn't any problem because we
don't have "user not found" errors in the clients.
