slapd permits unknown object classes with "schemacheck on"

[Thomas J Pinkl <tom@hbsrx.com>]

While playing with the MigrationTools from padl.com, I noticed that 
slapd in OpenLDAP 1.2.11 allows you to add entries of unknown objectClass 
when "schemacheck on" is specified in slapd.conf.

For example, it allows the addition of this entry:

    dn: cn=MAILER-DAEMON,ou=aliases,dc=domain,dc=com
    cn: MAILER-DAEMON
    rfc822MailMember: root
    objectClass: top
    objectClass: nisMailAlias

even though "nisMailAlias" is not defined as an object class in any of 
the schema configuration files.

Is this the expected behavior?
