Hi,

The issue is repeatable with a fresh install of a Debian 12 LXC container: [...]
The problem goes away if DynamicUser is commented out in service unit:
[...]
I have no idea why it would work in a VM and not in a LXC container.

I doubt this is a problem that will need a change in davmail. Container
related issues are usually not fixed in user applications.

What is the result of the following line in a LXC container?

(lxc)$ systemd-run --property=DynamicUser=yes /usr/bin/true

Are there any kernel messages (i.e. journalctl -t kernel) when the failure happens? We're looking for some permission denied stuff.

My guess is that your lxc setup requires extra permissions for this to work.

Thanks,

Alex

Nothing else displayed but that line.

Are there any kernel messages (i.e. journalctl -t kernel) when the failure

happens? We're looking for some permission denied stuff.

# journalctl -t kernel
-- No entries --

However, there were permission denied messages in the journal when I ran
the above command:

# journalctl -xe

Hi,

Relevant lines:

PR_SET_MM_ARG_START failed: Operation not permitted

run-rd2fa855982314217b00729153ec6dd8b.service: Failed to update dynamic
user credentials: Permission denied

run-rd2fa855982314217b00729153ec6dd8b.service: Failed at step USER spawning /usr/bin/true: Permission denied

This seems similar to this old issue.

What is your host kernel version?

What is your lxc conf?

Thanks,

Alex

Feeling like this is an old issue and not related to davmail, I'm closing this.

Feel free to come back to me if you feel like I'm wrong.

Cheers,

Alex
