Description:	This is a talk about building complex software that 'just works' for the vast majority of our users, lessons learned in that process and the complexity of managing a broad project that stretches from simple command line utilities to a whole Active Directory domain controller. Samba needs no introduction to most attending linux.conf.au, but it is worth explaining the full scope of the project, because our software is certainly used well beyond our mantra of "Opening Windows to a Wider World". Indeed, on many distributions uninstalling Samba (specifically tdb) uninstalls the whole desktop! Samba's progression up the stack starts with the provision of basic libraries like tdb and talloc to client tools and libraries (libsmbclient, libnet and others). Built on top of those are our file server, and what we call a 'classic' domain controller, the sort of like NT4. Further built on top of that is our Active Directory Domain controller, including Kerberos KDC and LDAP server, and beyond that are the hooks that projects beyond such as OpenChange reuse. All in all, it is a complex stack, but one that we must make 'just work', because the alternative (leave the administrator to piece together the parts) littered with horrible failures. Yet it is not an easy road, and has created a number of 'NIH' moments that have become embedded in our code-base. It is also a talk about upgrades, about unwritten and unenforced rules and where the rules of 'of course X is always true' meets the realities of deployed software on live networks. This will also be a talk with a few war-stories, the rules we expected our existing domains to honour, and how far from those expectations our users actually were, and the steps we have taken to help even the most idiosyncratic domain move on to become a Samba AD DC. I will argue for software that enforces restrictions rather than trusts that the administrator knows best. I will argue that in complex systems, that there should be one, scripted installation route to a working system, not a web-full of conflicting HOWTO documents, and that a secure, centralised authentication system should be easier to set up than the server it was installed on. markdown
