belongs_to
This defines a method for an extension class map its DN key attribute value on to multiple items which reference it by |:foreign_key| in the other LDAP entry covered by class |:class_name|.
Example:
belongs_to :groups, :class_name => "Group",
:many => "memberUid" # Group#memberUid
# :foreign_key => "uid" # User#uid
# dn attribute value is used by default
belongs_to :primary_group, :class_name => "Group",
:foreign_key => "gidNumber", # User#gidNumber
:primary_key => "gidNumber" # Group#gidNumber

#has_many(association_id, options = {}) ⇒ Object
has_many
This defines a method for an extension class expand an existing multi-element attribute into ActiveLdap objects. This discards any calls which result in entries that don’t exist in LDAP!
Example:
has_many :primary_members, :class_name => "User",
:primary_key => "gidNumber", # User#gidNumber
:foreign_key => "gidNumber" # Group#gidNumber
has_many :members, :class_name => "User",
:wrap => "memberUid" # Group#memberUid
