Question about ObjectClasses

["Mike Carpenter" <MCarpenter@roadwaynextday.com>]

I am currently experimenting with LDAP.
 My company would like to use it as a central point of administration
for our Radius, Samba & Squid servers.  However something I was
reading in the samba.schema file about objectclasses and LDAPv3 has me
wondering:

Can an LDAPv3 record have more than
1 objectclass?   The samba.scheme file makes mention that starting
in OpenLDAP 2.1, records will only be allowed one objectclass.

Currently my test records have 3 objectclasses
(person, radius, sambaaccount).  This is so I can access the attributes
needed for each of the applications for each user DN.   Is this incorrect?

Thanks
