I'm using this solution on a high profile client right now, and the lack of support for integrated authentication(kerberos/windows) is a major issue.

I'm using the .net wrapper, but the underlying implementation needs to support this feature as well. Tried using an authentication proxy but wasn't able to make it work as well.

Kind regards

I will add this to the roadmap for future investigation.

For the record, Prince 10 now has support for Windows authentication.
