# create-user.sh — create a user in LLDAP and add them to net-kingdom-users
#
# Usage:
# ./create-user.sh <username> <email> [display-name] [--admin] [--test] [lldap-url] [secrets-dir]
#
# <username> LDAP uid — e.g. "bernd" or "testuser"
# <email> e.g. "bernd@coulomb.social"
# <display-name> defaults to <username>
# --admin also add to net-kingdom-admins
# --test set password automatically as <DisplayName-Pwd> (spaces→hyphens)
# e.g. display "Test User" → password "Test-User-Pwd"
# <lldap-url> default: https://lldap.coulomb.social
# <secrets-dir> default: ../../bootstrap/secrets
#
# Examples:
# ./create-user.sh testuser test.user@coulomb.social "Test User" --test
# ./create-user.sh bernd bernd@coulomb.social "Bernd W" --admin
