I was able to solve this by specifying userdb use the passwd-file in addition
to passdb using bsdauth:
userdb {
args = username_format=%u /etc/passwd
default_fields = quota_rule=*:storage=1G
driver = passwd-file
}
This is combined with:
passdb {
driver = bsdauth
}
This may be an ugly solution but it does seem to work and only requires me
maintain a single passwd file.
