add entry with two objectclasses failed

["Joe Wong" <joewong@tkodog.no-ip.com>]

Hi,

 

 I am trying to add an entry with two objectclasses:

 

objectclass=a

objectclass=b

However, OpenLdap returns error 20 ( attribute provided more than once ). How can I resolve this? Or I am not doing the thing correctly?

Thanks!
