For what it's worth, there is a multitude of software that can manage SSH pubkey distribution. If you're using SSSD with AD/LDAP auth, you can even store users' SSH pubkeys in the directory itself bound to their user object and SSSD can dynamically fetch it/them at runtime directly.

I've seen orgs use LDAP to manage authorized_keys or the equivalent.  Does anybody do some kind of federated authentication with ssh, like OIDC/etc?  

I'm not sure how useful it would be for me at home, since I'd want to be able to use ssh to troubleshoot the authentication service - there are just some infra items you don't want too many dependencies with.  I'm just curious what is out there, and since the list is low-traffic I figured I'd start a conversation here instead of chatting with an LLM about it.  :)
