Multiple Instances on Subdomains sharing domain

Hi,
It’s been a while that I’m asking myself if it would be possible to do:

mastodon1.example.org
mastodon2.example.org

Each one of them having their own login website, but all of them sharing same @example.org

For example, for schools:

schoolname1.schools.org
schoolname2.schools.org

Would they need to share database? Would be that possible with LDAP?

Thanks

You can use LDAP to log in, but you cannot share the identifier. If the message should go to johnny@schools.org, which instance should receive it?
