Thanks for clarifying. Systemd should support resolving users via LDAP, with a caveat: the service providing the users should be running when the user resolution is requested [1]. This may be a problem at boot time, but not once the boot has completed. This is why I was insisting on trying to start the service after the boot process was complete.
As it *should* be quick and easy I'd give a shot at replacing libnss- ldap with libnss-ldapd. From [2]: libnss-ldap has some known issues with serving host information and lookups during boot which should be addressed in libnss-ldapd.
