Per lechner suggestion at #debian-devel @ IRC, let me share here a potential
root cause for this issue.
The nsswitch.conf file is different inside/outside the schroot:
(bullseye-amd64-sbuild)root@tools-package-builder-04:/build/toollabs-webservice-Oe7KMY#
cat /etc/nsswitch.conf
# /etc/nsswitch.conf
#
# Example configuration of GNU Name Service Switch functionality.
# If you have the `glibc-doc-reference' and `info' packages installed, try:
# `info libc "Name Service Switch"' for information about this file.
