Re: "user with UID not found" error

Hi Ricardo,

Turns out we are using SSSD not NCSD on our Linux systems. It seems to be working fine:

  % service sssd status
  ...
   Active: active (running) since Sat 2022-01-15 15:02:04 EST; 6 months 9 days ago

Note that this works fine:

  % id --user
  317241
  % id -nu 317241
  cb535

Do you think there is any issue with the fact that my user ID is 317241, and that is greater than 65535?

Hmmm ... I tried this too:

  % guile
  scheme@(guile-user)> (getpw 317241)
  $1 = #("cb535" "*" 317241 123123 "Christopher Batten" "/home/cb535" "/bin/bash")

And that works fine.

Does this have something to do with how guix interacts with LDAP?

I am pretty confused why getpw works in guile but guix is saying "user with UID 317241 not found". I don't know enough about the guix internals to try and debug it ... maybe this has something to do with this UID is not available when the guix daemon is doing some of its magic?

Thoughts?
Chris
