What's your problem ? That's exactly what your ldap record should look 
like. A (base_dn, record) tuple, where the record is a dict of 
attribute_name:[values, ...]

Q&D wrapper:

class LdapObject(object):
   def __init__(self, ldapentry):
     self.dn, self._record = ldapentry

   def __getattr__(self, name):
     try:
       data = self._record[name]
     except KeyError:
       raise AttributeError(
         "object %s has no attribute %s" % (self, name)
        )
     else:
       # all LDAP attribs are multivalued by default,
       # even when the schema says they are monovalued
       if len(data) == 1:
          return data[0]
       else:
          return data[:]

   def isa(self, objectClass):
     return objectClass in self.objectClass:

root = LdapObject(
   ('dc=example,dc=com',
    {'objectClass': ['top', 'dcObject','organization'],
     'dc': ['example'],
     'o': ['Example Organisation']}
   ))

root.o
=> 'Example Organisation'
root.objectClass
=> ['top', 'dcObject','organization']
root.isa('organization')
=> True

FWIW, I once started writing an higher-level LDAP api (kind of an 
Object-LDAP Mapper...) using descriptors for ldap attribute access, but 
I never finished the damned thing, and it's in a very sorry state. I'll 
have to get back to it one day...

cf above.
