c.send("#{k.downcase}=", v) is the right thing to do and it is normal if it is saved as :
'--- 
- inetLocalMailRecipient
- person
- posixAccount
- sambaSamAccount
- shadowaccount
- top
'

It's just because it is saved into the yaml format
Just get back the LdapAccount you just saved and you will see that the objectclass attribute will be an instance of Array
