Remove Cyrus SASL from XMPP
Review Request #2295 — Created Feb. 26, 2023 and submitted — Latest diff uploaded
This will eventually be replaced by Hasl, but XMPP has it's own built-in SASL mechanisms as well as Cyrus, so removing Cyrus first is just the first step.
Connected an XMPP account, sent direct messages from both sides, and joined a muc and sent messages from both sides as well.
Also ran the unit tests.
