Looking for some kind of SSO/Account Management for TrueNAS - eviltoast

I have 2 x TrueNAS boxes, and because I am doing replication between them, I need to keep the UID’s and GID’s the same between them for accounts that are needed on both ends

This leads to a situation where I must great all accounts on both sides, which gets a bit annoying.

There is also situations where I need to update accounts, like my wifes account, but she has no access to TrueNAS, so I need to get to her type her password in, twice. A bit annoying

I’d love a way to have a central account repository with a self serve password changing UI so people can change their password, and have it all sync between TrueNAS. Ideally the accounts would stay on TrueNAS, so if the SSO solution dies, all the accounts stay

Does this exist?
