Hello,
I am in the process of moving a previously working dovecot setup to a
new authentication system. The identity management system, kanidm, uses
a Pam module and NSS backend to provide user info. Authentication works
normally on the machine, but Dovecot is having a lot of trouble, logging:
Error: Invalid uid in reply
Error: Invalid gid in reply
I ran doveadm -D user je...@waffle.tech as a test, and I see:

We can see the UID and GID in the debug output, but it comes out blank
in the final info. I'm having a hard time finding what the cause could
be, is it possible that these UID/GID values are too large? that's about
the only thing I can think of right now.
This is Dovecot 2.3.21 (47349e2482) on Fedora 39.
Thanks,
jc
