Looking for a Linux-Based Backup Domain Controller Compatible with Active Directory

Asked By TechieTraveler42 On

I'm a huge fan of open-source software, and at my current job, finding the right backup solutions has become a pressing issue. We have three Windows Server 2019 machines acting as Domain Controllers across various locations, but I'm concerned that this setup might not be sufficient. We want to avoid relying on cloud solutions or incurring extra costs. FreeIPA seems like it could handle both POSIX and NT systems, but unfortunately, it doesn't support Windows machines. The only alternative I've come across is Samba DC, but I'm worried about its compatibility with Windows Server 2019 and its failure to replicate the SysVol directory based on their documentation. I'm really looking for a free or open-source solution that doesn't involve virtual machine replication or cloud services. To give some context, we operate about 110 Windows computers and around 20 Unix-like systems across two offices, so it's not a massive network. Also, a portion of our machines are thin clients for our ERP and WMS systems, which we might replace with Linux setups in the future.

While I've played around with Samba DC in the past, I found it lacking for larger setups. It worked fine for a small office, but I often felt uneasy about updates potentially breaking the system. If you need group policies or extensive management features, sticking with Windows Server might be the better choice.

I get where you're coming from with wanting to avoid cloud solutions, but I would advise against using Samba as a domain controller for a mission-critical setup like yours. It might lead to serious issues down the road. Instead, maybe explore other identity platforms that can better suit your needs or just confirm with your management about sticking with a robust Windows solution for now.

Honestly, it’s crucial to stick with technologies that are well-supported, especially when your infrastructure depends heavily on Active Directory. If you’re not open to using Windows Server, I’d suggest considering different setups that fit your network better instead of risking using Samba DC.
