Microsoft has entered into a licensing agreement with the nonprofit Protocol Freedom Information Foundation (PFIF) under which the software giant will be providing developers working on the Samba file and printing system with the information they need to ensure interoperability between their open-source software and Windows.

Essentially, the agreement gives the Samba team access to Microsoft specifications for the protocols in the Work Group Server Protocol Program and allows the Samba team to create, use, and distribute implementations.
