I'm out of ideas. More eyes please ? It seems peculiar to me that the log shows login success, but the oops message says it can't auth. I'm not very familiar with the inner workings of vpopmail though. Have you found where in the code the oops messages is being issued? -- -Eric 'shubes' !DSPAM:51c5b3d734139722810834!

Re: [vchkpw] odd problem after OS upgrade (hey, Tom, Ken, jkitchen: around?)
Did you recompile qmail and vpopmail after the OS upgrade? I'm wondering if it's something odd where the size of some data type changed from 32 to 64 bits after the OS upgrade, and one program is using the new size (perhaps because of a dynamically linked library) and the other is still using the old size. That's my best guess. I haven't been doing POSIX development in a long time, and even when I did I didn't wade too far into spawning children and exit codes. But it seems like the successful exit code isn't being interpreted correctly on qmail-smtpd. -Tom On Jun 22, 2013, at 6:11 PM, Jeremy Kister wrote: On 6/22/2013 8:26 PM, Jeremy Kister wrote: i'm not even sure it's a vpopmail problem, i suppose i may need a cross post on the qmail list. hrm. i replaced vchkpw with checkpasswd. still broken. -- Jeremy Kister http://jeremy.kister.net./ !DSPAM:51c68c1e34131709335937!
