Support for the choice structure

Hi, I'm trying to implement on go getting a keytab in an IPA. The documentation says that I need to implement an extended operation and encrypt the data for it using asn1. Can you tell me with the help of this library is it possible to do this?

This is the wrong repository, but see go-ldap/ldap#516 as I'm already trying to implement the extended operation into the go-ldap library. I haven't got the time to finish it of but you're free to review the code, test it and give some feedback :)
