This script works fine when I call it from the command line as the dhcpd user but when called from the dhcpd daemon it throws a WERR_INTERNAL_DB_ERROR which is scary. That is coming from the client I guess. What is the best way to figure out what is going on server side. I increased the log level but I get crazy amounts of info that does not seem relevant.

It’s better, now I just get a SERVFAIL like it can’t find it. If I do a samba-tool query ALL I see records in the AD.
