```ruby
module MIT
  module LDAP

    class << self
      attr_accessor :connection
    end

    def self.connect!
      if MIT.on_campus?
        self.connection = ::LDAP::Conn.new('ldap-too.mit.edu')
        singleton_class.send(:include,
          Ldaptic::Module(
            :adapter => :ldap_conn,
            :connection => connection,
            :host => 'ldap-too.mit.edu',
            :base => 'dc=mit,dc=edu',
          )
        )
      end
      return !self.connection.nil?
    end
  end
end
```

Add LDAP.connected? method for easily checking if connected
user
```ruby
module MIT
  module LDAP

    class << self
      attr_accessor :connection
    end

    def self.connect!
      if MIT.on_campus?
        self.connection = ::LDAP::Conn.new('ldap-too.mit.edu')
        singleton_class.send(:include,
          Ldaptic::Module(
            :adapter => :ldap_conn,
            :connection => connection,
            :host => 'ldap-too.mit.edu',
            :base => 'dc=mit,dc=edu',
          )
        )
      end
      return connected?
    end

    def self.connected?
      !self.connection.nil?
    end
  end
end
```
