change structural objectClass to another

[Galoppin Fabian <fgaloppin@altern.org>]

Hello list,

	I want to change some objectClasses for an entry in my ldap but
It doesn't run correctly... 
I want to delete objectClasses 'top' and 'account' and replace them
with 'inetOrgPerson' 'person' and 'organizationalPerson'...

I think it is a problem with structural objectClasses 'account' and 'inetOrgPerson'
but if i replace a structural by another... I thought that was right...
