DHCP IP-Reservation and Dynamic DNS Update Hi @ ALL before I've started to get known with LDAP, I had nearly the same setup in my network enviroment without LDAP. And I used the rcnd.key function so that DHCP and DNS could work together so that DHCP updated dynamic the dns zones. I've been also able to use reservation in conjuction with the MAC Address for some host so that they will only got a specified IP Address. Now I am wondering who can I (we) uses this feature with this LDAP Setup? Something like that for host IP reservation e.g.: Code: dn: cn=stka, cn=DHCP Config, dc=lokal,dc=de cn: stka objectClass: top objectClass: dhcpHost dhcpHWAddress: ethernet 00:0a:e4:22:af:de dhcpStatements: fixed-address 192.168.123.3 But how about the dns zone dynamic update? Maybe someone can give me a hint on that please.
