# Script to determine the next subuid / subgid for a user.
# It will consider (a) all already existing subuid / subgid ranges and (b) all "real" user ids.
#
# Note: When using LDAP login (e.g. with SSSD), /etc/passwd won't contain those external users.
# In the case of SSSD, you will have to enable enumeration (https://access.redhat.com/solutions/500433) to make "getent passwd" all local AD / LDAP users.
# However, on the other hand, enabling recommendation is not recommended, because it will cause high load on server and client (https://docs.pagure.org/sssd.sssd/users/faq.html#when-should-i-enable-enumeration-in-sssd-or-why-is-enumeration-disabled-by-default).
