For webapp stuff for sure, but when you want to login as the same user with the same perms across all your VMS and baremetal servers at the os, it’s nice.

I use virtualization over containerization because i have the hardware resource so I might as well take advantage of improved isolation and security VMS provide. Plus I use Linux on my desktop/laptop, and have a separate dedicated storage host.

Its nice to have everything managed by one service with global accounts and permissions.

Looking at authentik it seems to provide some but not all of that. Def something to keep an eye on if freeipa decides to stop being so free.
