Hmmm...can't seem to make that happen....

class LdapAccount < ActiveRecord::Base
  serialize :objectclass, Array
end


I think because I'm wrapping the value in quotes turning the Array v to a String when it's saved in the model...
c.send("#{k.downcase}=", "#{v}")

Produces...
objectclass was supposed to be a Array, but was a String


I can't take the quotes off though because it doesn't save correctly in the database.  Using this code, entries end up looking like this when I don't wrap v in quotes.
c.send("#{k.downcase}=", v)

'--- 
- inetLocalMailRecipient
- person
- posixAccount
- sambaSamAccount
- shadowaccount
- top
'

You should try to serialize your array instead of saving it as a string
if you are using ActiveRecord try this :
class LdapAccount < ActiveRecord::Base
  serialize :mails, Array
end

then when you get the accout from the database :
my_account.mails return an Array
