SaslServ "LOGIN (session timed out)" log messages are useless

[lstarnes1024]

One of my networks has a few users who are on unstable connections, so their client keeps reconnecting and timing out during SASL authentication. This is causing our services log channel to be full of LOGIN (session timed out) messages from SaslServ, and there are about 20 of those messages for every successful LOGIN message. Additionally, the timeout happens during connection registration, so my ircd (charybdis) doesn't even log what IP they're using so I can impose a D-Line, but I don't think it's fair to do that. As a network admin, I don't have the ability to fix these clients. The log message also does not provide any value because it's not a successful authentication or even a completed but failed attempt, which could be a sign of a user's account being attacked.

Suggested fix: remove the below part of sasl_session_destroy or provide a configuration option to disable this message without disabling the other SaslServ messages:

if (mu && ! (ircd->flags & IRCD_SASL_USE_PUID))
    (void) logcommand(p->si, CMDLOG_LOGIN, "LOGIN (session timed out)");
