I cannot find any reference to this error anywhere. I keep getting "dhcpd: getentry.c:46: ldap_next_entry: Assertion `ld != NULL' failed." when starting isc-dhcp-server, and the program exits. I have spent a lot of time trying to find a reference to this on the Internet, to no avail, so I don't even know where to start or what information is needed to figure this out.
I am running Ubuntu version 19.04, and isc-dhcpd-server-ldap 4.4.1 installed via apt from the standard repositories.
