As a followup to this thread, it is looking increasingly like this is a regression in glibc-2.28. One of the Gentoo devs has reproduced the problem, created a test case and bisected it down to a specific commit that went into glibc in July. For more information see: https://bugs.gentoo.org/667118 Note: it's not a problem with glibc-2.27, but new to 2.28. Reuben On 19/09/2018 6:53 pm, Aki Tuomi wrote:
I have no idea why it's returning invalid argument, maybe you need to raise this as issue with glibc?

Can you provide your /etc/nssswitch.conf?

I've been running with this almost identical patch already for some time:

That fixed the build problem I had, but the warning below remains.

This is bit of a longshot, but can you try applying https://github.com/dovecot/core/commit/63a74b9.patch and see if this helps?

glibc-2.28.
There was a posting by Michael Marley on 31/08 saying he saw something similar to this problem after upgrading to 2.28 as well with 'doveadm purge'.
