|
# Objects of this class represent individual entries in an LDAP
|
|
# directory. User code generally does not instantiate this class.
|
|
# Net::LDAP#search provides objects of this class to user code,
|
|
# either as block parameters or as return values.
|
|
#
|
|
# In LDAP-land, an "entry" is a collection of attributes that are
|
|
# uniquely and globally identified by a DN ("Distinguished Name").
|
|
# Attributes are identified by short, descriptive words or phrases.
|
|
# Although a directory is
|
|
# free to implement any attribute name, most of them follow rigorous
|
|
# standards so that the range of commonly-encountered attribute
|
|
# names is not large.
|
|
#
|
|
# An attribute name is case-insensitive. Most directories also
|
|
# restrict the range of characters allowed in attribute names.
|
|
# To simplify handling attribute names, Net::LDAP::Entry
|
|
# internally converts them to a standard format. Therefore, the
|
|
# methods which take attribute names can take Strings or Symbols,
|
|
# and work correctly regardless of case or capitalization.
|
|
#
|
|
# An attribute consists of zero or more data items called
|
|
# <i>values.</i> An entry is the combination of a unique DN, a set of attribute
|
|
# names, and a (possibly-empty) array of values for each attribute.
|
|
#
|
|
# Class Net::LDAP::Entry provides convenience methods for dealing
|
|
# with LDAP entries.
|
|
# In addition to the methods documented below, you may access individual
|
|
# attributes of an entry simply by giving the attribute name as
|
|
# the name of a method call. For example:
|
|
# ldap.search( ... ) do |entry|
|
|
# puts "Common name: #{entry.cn}"
|
|
# puts "Email addresses:"
|
|
# entry.mail.each {|ma| puts ma}
|
|
# end
|
|
# If you use this technique to access an attribute that is not present
|
|
# in a particular Entry object, a NoMethodError exception will be raised.
|
|
#
|
|
#--
|
|
# Ugly problem to fix someday: We key off the internal hash with
|
|
# a canonical form of the attribute name: convert to a string,
|
|
# downcase, then take the symbol. Unfortunately we do this in
|
|
# at least three places. Should do it in ONE place.
