Greetings, I've noticed this on two separate installations of qmail/vpopmail/sqwebmail (all latest versions); after the authdaemon has been started, all virtualusers can log into the sqwebmail interface reliably for a while.
Then after a period of several hours, random users will start getting "invalid user ID or password" errors when they try to log in with known good username/password errors. Meanwhile, they can all still log in with POP clients without a problem. I'm seeing this on both a RedHat 6.2 box and a RedHat 7.3 box. If I restart the authdaemon, the problem goes away again for a time. I've tried recompiling sqwebmail, without any options and with the options: "--without-module-authdaemon" and "--with-module-vchkpw" however, authdaemond was still built and sqwebmail still wouldn't work without it running. I would like to deploy these systems as live servers, but that's out of the question as long as they have this kind of reliability problem. Any pointer/suggestions would be greatly appreciated. TIA, --Duncan
