Encoding::UndefinedConversionError

[Ajedi32]

I recently started trying to implement a LDAP-based login system in my Rails application, but whenever I try to run a basic LDAP query I get the following error:

Encoding::UndefinedConversionError: "\x82" from ASCII-8BIT to UTF-8
        from c:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/net-ldap-0.3.1/lib/net/ber/core_ext/string.rb:23:in `encode'
        from c:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/net-ldap-0.3.1/lib/net/ber/core_ext/string.rb:23:in `raw_utf8_encoded'

        from script/rails:6:in `<main>'

It seems to be triggered whenever net-ldap hits a certain record in the ldap database (though I can't really tell which one). Here's the code I'm running that triggers the error. It always gets to a certain point and then errors out:

    test = LDAP.search(
      base: BASE_ROOT, # This is defined elsewhere in my code.
      attributes: ["mail"],
      filter: Net::LDAP::Filter.eq("objectClass", "person"),
      return_result: true,
      size:300
    ) do |entry|
      puts "DN: #{entry.dn}"
      entry.each do |attribute, values|
        puts "   #{attribute}:"
        values.each do |value|
          puts "      --->#{value}"
        end
      end
    end

Is this a bug? Or is there something I'm doing wrong?

I figured out how to solve the problem, this is indeed a bug: https://github.com/ruby-ldap/ruby-net-ldap/pull/44

I'll be using krogebry's branch of net-ldap until this problem is fixed.

Glad I could help!

I tracked this down to ( I think ) some Microsoft specific garbage in one of the returned fields.

Now I'm trying to figure out how to get my patch rolled into the next rev.
