Necessity is the mother of invention
After posting my earlier project, where I pulled a small, open-source infrastructure out of a hat for a small business that had nothing and now has real infrastructure, some people reached out and started asking questions. One of those turned into a hands-down agreement on a job.
A tight budget and no Windows Domain
One of the people who reached out was a business owner I know personally. They run a small local company with about 10 Windows PCs, a few printers, one NAS, and a lot of sensitive data handled daily. Budget is tight, and the owner has no interest in cloud-based identity services like Azure AD or M365.
