Ruby on Rails
LDAPFunctions

LDAP can be used within Rails by leveraging the Ruby/LDAP module located at http://ruby-ldap.sourceforge.net.

Example

require "ldap" 

LDAP::Conn.new("ldap.mycompany.com", 389).bind { |conn|
  begin
    conn.search("ou=MyOrgUnit, o=MyOrg", LDAP::LDAP_SCOPE_SUBTREE, "(cn=Joe Shmo)") { |record|
      #do whatever with the record matched, here I just print it out
      p record.vals("cn")
    }
  rescue LDAP::ResultError => msg
    $stderr.print(msg)
  end
}
