"Unauthorized" IP address assignments
There is an option for the DHCP Server object called "Ping Enabled". If this option is selected the DHCP Server will Ping the first address before handing out that address to a client. If the DHCP Server receives a response to the Ping, meaning that address is in use already, the DHCP Server will create an IP address object of type "Unauthorized". This simply tells the DHCP Server not to hand out this address for now.
You can deleted them via the DNSDHCP java console but you don’t have to. Every 4 hours it checks to see if they are free and releases them if they are. (TID 10014757)

With the old version, you had to do this manually by creating static address assignments using a bogus host names like BLOCKER.

Lame delegation found (DNS)
When the NetWare 5 DNS server loads it attempts to resolve the NS (name server) records in each of the configured zones. It looks for an "A" record that has the NS record name and an IP address of the actual DNS server. If the DNS server cannot resolve the NS record name it will display a message stating there is Lame delegation found in some name server record in some zone. The message tells you what record and zone the problem is with.

Fix - Create an "A" record for the NS record and this message will not appear anymore. This is why when creating a zone object you get a message telling you not to forget to create a corresponding "A" record for this zones name server. (TID 10022558)

Why don’t existing addresses leases get added to the DNS database?
For each existing IP addresses that are dynamically assigned you cannot click the Enable DNS RR Entry Updates box. Even if you have everything configured right only NEW leases get that box automatically checked. Old addresses must expire or be deleted first.
