Is it possible the errno came from elsewhere somehow?
The error is reproducible, and only happens with this account (in ~6 weeks of log files). For this account, it happens from different client machines, and MUAs.
Does this have auth_debug = yes?
Yes, hence the verbosity.
Any chance you can run a test with current release 2.4.1 or git head to see if it exhibits similar issues?
It's a production machine. And since the recent comments here give me the impression that 2.4 should really have been called 3.0 Alpha, I think I'll pass.
Not a dovecot dev, but if were me and debug logs did not reveal enough, I'd add some debugging print statements to src/lib/ipwd.c (thats where the 2.4.x call to getpwnam_r() is) to try figure out what is actually happening. I did not look to see how similar the old 2.3.x code is to 2.4.
Thanks, I'll have a look at the code.
Cheerio, Hauke
