Hi Davide,

Sorry for the delay; it looks like your bug report fell through the
cracks.

Davide Corrado <davide.corrado <at> doit-systems.it> skribis:

> hello, I installed guix in a HPC environment and everything works as expected if I use guix as a local user. I got this issue when I try to run it as an openldap/sssd-managed user.

I think this message shows the core of the problem.

Is nscd running on this machine, as per
<https://guix.gnu.org/manual/devel/en/html_node/Application-Setup.html#Name-Service-Switch-1>?

It has to be installed and running so that Guix-installed programs can
access the user account database etc.

A simple way to check whether this is working is by running the ‘id’
program of the ‘coreutils’ package provided by Guix, like so:

  guix shell coreutils -- id

HTH!

Ludo’.
