NET::LDAP and Rails Session

Does anybody know what the correct way to cache results from
Net::LDAP bind_as? I’ve been struggling for about a day now and I
know it’s something really easy. But when ever I do something like
this -

def self.login(username, password)
begin
ldap = Net::LDAP.new
ldap.host = “192.168.1.16”
ldap.port = 389

 result = ldap.bind_as(
   :base => "dc=net",
   :filter => "(cn=#{username})",
   :password => password
 )

 @dn = result.first.dn
 rescue => e
     false
  end

end

and in my controller I do

if request.post?

   session[:user_id] = AuthUser.login(params[:user]["username"],

params[:user][“password”])

end

My server returns a 500 error. I’ve tried from lighttpd and
locomotive. Both return the same generic error. I suspect it’s
related to the object returned is not compatible with the
marshal_dump. So the question is how do I copy the values from the
result set into my session object? Sorry if this is a stupid noobie
question but I am one so. :slight_smile:

Thanks in advance.
