unified usernames

can you set your federation domain separate from its hosted domain?

matilde@sunshinegardens.org while still logging onto social.sunshinegardens.org?

• https://github.com/tootsuite/documentation/blob/archive/Running-Mastodon/Serving_a_different_domain.md

email and xmpp are already sharing @sunshinegardens.org. we'll need to fix pleroma to federate over the root domain. hopefully this doesn't involve a db reset or migration.

in the future, we can also support SSO.

whipping up an LDAP server in python. when ssb support is available in sora we can integrate the id server with @etc so they can manage id stuff for us.
