I'd like this to be merged, so #12247 could be closed. I could then add the callback to matrix-synapse-ldap3 auth backend, making the latter a 100% replacement for the dead ma1sd, at least in a LDAP based setup.

Is there no docs needed for synapse/docs/modules/?

[Samonitari]

Fair enough - I'll add the docs, and remove the commented out loop!

Cool, thank you for the PR 🥳

We also need this feature, thus your PR looks very promising. Keep up your good work! Looking forward to get it into Synapse 😃

@Samonitari or @janpawellek -- do you wish to continue this PR? It looks like it needs some updates and the feedback addressed.

[Samonitari]

Yes, but to be a bit more direct - and to not make any bloody estimation lies - sometime this year I'll do this. I'll keep you updated, but the next two weeks I am consolidating two hosting servers into one - I am halfway there!
