DDNS Not Working When Using LDAP Config

[puregore]

Is this for LDAP-based forward/reverse domains or for some additional domain that is file-based? Last time I checked, the LDAP backend of named wasn't capable of doing writes, it was for lookup only.

This is for an LDAP-based forward/reverse domain.

If the LDAP backend of named can't do writes, then why am I able to update the records manually using nsupdate and a TSIG key? Doesn't dhcpd use the same mechanism as nsupdate to do its updates? (I forget the name of the mechanism now)
