I have a model that uses net-ldap for communication to an Active Directory server, and after upgrading the gem from v0.2.2 to v0.3.1, I get a Encoding::UndefinedConversionError exception when binding and performing a query. When I downgrade to 0.2.2, the problem goes away instantly. It looks like it may be due to the recent changes to use UTF-8 string encoding by default.

It seems that my application encounters this only when I am searching AD using a GUID, which would indicate that net-ldap is trying to convert the binary GUID to UTF-8.
