uid not useable for LDAP_USER_DEFAULT_ATTRIBUTES
{loginname}
and such is fine, but any attribute being set by the default=
function of an ldap attribute is None.
It seems the add_hook of the Attribute gets called after the add_hooks of the Model in ldapalchemy. @julian could you check that out, I could not determine the error here...
(is a mix of uffd and ldapalchemy. I decided for a bug here...)
