![]() ![]() Example: Adding a PTR record to the 192.168.0.0/16 reverse zone.Example: Adding a PTR record to the 192.168.0.0/24 reverse zone.Your new zone will be directly live without restarting Samba or BIND. To create a /16 reverse zone # samba-tool dns zonecreate To create a /24 reverse zone # samba-tool dns zonecreate 0. For instance, using 192.168.0.0/24 (netmask 255.255.255.0) will you allow you to have a maximum of 254 ipaddresses. You can, if you so wish, use different Subnet masks/CIDRs to split up the RFC1918 zones. The third: 192.168.0.0/16 will allow you to have a maximum of 65,534 ipaddresses. The second: 172.16.0.0/12 will allow you to have a maximum of 1,048,574 ipaddresses. Using the first one: 10.0.0.0/8 will allow you to have a maximum of 16,777,214 ipaddresses. It is suggested that you use, wherever possible, one of the RFC 1918 zones, these are: Do not use anything else between your clients and Domain Controller/s.Īdministering DNS on Linux/Unix with samba-tool Creating a new zoneĪs an example we'll add a reverse lookup zone. Clients find their Domain Controller/s and other important AD services by DNS queries, this means that your clients must use your Domain Controller/s as their nameservers. It's not just for resolving IP addresses into names and vice versa. Bug report #9634: Samba Bind DLZ module allows zone transfers for everyoneĪ working Active Directory is heavily based on a working DNS. Different zone transfer settings on internal DNS (denied) and BIND DLZ (allowed).Bug report #9951:DNS MMC: Enabling DNS zone transfers in MMC fails Managing zone transfers is not implemented yet.Įven though the internal DNS and the BIND DLZ modules are new, they both support all basic requirements for Active Directory and more. If you discover problems or missing features, please open a bug report/feature request at. That's why both backends don't yet cover all the features that you can setup with the Microsoft DNS tools. Although BIND is a grown up DNS and long in production on millions of servers, the Samba BIND DLZ module is still new. The Samba internal DNS is a new implementation. _: This is the ForestDNSZone, that contains several service records for the entire directory.You will already find general information on the internal DNS and the BIND DLZ module and documentation about Bind as DNS Backend in the Wiki.īy default, Samba creates the following two forward zones during provisioning/upgrading (of course with your own domain name): If you're running Samba as Active Directory Domain Controller, you also have to administer a DNS server. 8 Configuring clients to use your AD DNS server.7 Administering DNS on Linux with admin-tools.5 Administering DNS on Linux/Unix with samba-tool.4 Importance of DNS for Active Directory.The computer is now ready to access the share from a Windows computer and log on with an Active Directory account. Create a dns entry for the Samba server: /opt/pbis/bin/update-dns.Make sure the path exists and permissions for the share are set:Ĭhown DEMO\\pbisadmin:DEMO\\pbis_group /share.Run the testparm command to make sure smb.conf contains no syntax errors.Create a new section to define a shared resource and constrain access to the Active Directory group pbis_group.If an alternate hostname is used, then set that hostname as the NetBIOS name: netbios name = CENTOS-TEST.If the machine password option is not added to the smb.conf and set to 0, Samba will change the machine account password without notifying the AD Bridge authentication service, leaving AD Bridge unable to connect to the domain. The realm is the computer's Active Directory domain. ![]() The workgroup is the computer's NetBIOS domain name. Replace the values of workgroup and realm with the values for the network. The ADS value for the security setting is required. On the Linux or Unix computer that is running Samba, add the following settings to the global section of the Samba configuration file (Typically located at /etc/samba/smb.conf):.Configure Samba on a Linux or Unix Computer
