Manage Samba. 4 AD Domain Controller DNS and Group Policy from Windows. Continuing the previous tutorial on how to administer Samba. Windows 1. 0 via RSAT, in this part well see how to remotely manage our Samba AD Domain controller DNS server from Microsoft DNS Manager, how to create DNS records, how to create a Reverse Lookup Zone and how to create a domain policy via Group Policy Management tool. Requirements. Create an AD Infrastructure with Samba. Ubuntu 1. 6. 0. 4 Part 1. Manage Samba. 4 AD Infrastructure from Linux Command Line Part 2. Manage Samba. 4 Active Directory Infrastructure from Windows. RSAT Part 3. Step 1 Manage Samba DNS Server. Samba. 4 AD DC uses an internal DNS resolver module which is created during the initial domain provision if BIND9 DLZ module is not specifically used. JenkinsWinstone Web8080JenkinsSSL. The site for people who want to establish the Network Server with CentOS, Ubuntu, Fedora, Debian. C400' alt='Install Squid Reverse Proxy Centos' title='Install Squid Reverse Proxy Centos' />Samba. DNS module supports the basic features needed for an AD Domain Controller. The domain DNS server can be managed in two ways, directly from command line through samba tool interface or remotely from a Microsoft workstation which is part of the domain via RSAT DNS Manager. Here, well cover the second method because its more intuitive and not so prone to errors. To administer the DNS service for your domain controller via RSAT, go to your Windows machine, open Control Panel System and Security Administrative Tools and run DNS Manager utility. Once the tool opens, it will ask you on what DNS running server you want to connect. Choose The following computer, type your domain name in the field or IP Address or FQDN can be used as well, check the box that says Connect to the specified computer now and hit OK to open your Samba DNS service.

Connect Samba. 4 DNS on Windows. In order to add a DNS record as an example we will add an A record that will point to our LAN gateway, navigate to domain Forward Lookup Zone, right click on the right plane and choose New Host A or AAA. Add DNS A Record on Windows. AtzZoh6.png' alt='Install Squid Reverse Proxy Centos' title='Install Squid Reverse Proxy Centos' />On the New host opened window, type the name and the IP Address of your DNS resource. The FQDN will be automatically written for you by DNS utility. When finished, hit the Add Host button and a pop up window will inform you that your DNS A record has been successfully created. Make sure you add DNS A records only for those resources in your network configured with static IP Addresses. Dont add DNS A records for hosts which are configured to acquire network configurations from a DHCP server or their IP Addresses change often. Configure Samba Host on Windows. To update a DNS record just double click on it and write your modifications. To delete the record right click on the record and choose delete from the menu. In the same way you can add other types of DNS records for your domain, such as CNAME also known as DNS alias record MX records very useful for mail servers or other type of records SPF, TXT, SRV etc. Step 2 Create a Reverse Lookup Zone. By default, Samba. Ad DC doesnt automatically add a reverse lookup zone and PTR records for your domain because these types of records are not crucial for a domain controller to function correctly. Instead, a DNS reverse zone and its PTR records are crucial for the functionality of some important network services, such as an e mail service because these type of records can be used to verify the identity of clients requesting a service. Sql Concatenate Rows Microsoft Access. Practically, PTR records are just the opposite of standard DNS records. The clients know the IP address of a resource and queries the DNS server to find out their registered DNS name. In order to a create a reverse lookup zone for Samba AD DC, open DNS Manager, right click on Reverse Lookup Zone from the left plane and choose New Zone from the menu. Create Reverse Lookup DNS Zone. Next, hit Next button and choose Primary zone from Zone Type Wizard. Select DNS Zone Type. Next, choose To all DNS servers running on domain controllers in this domain from the AD Zone Replication Scope, chose IPv. Reverse Lookup Zone and hit Next to continue. Select DNS for Samba Domain Controller. Add Reverse Lookup Zone Name. Next, type the IP network address for your LAN in Network ID filed and hit Next to continue. All PTR records added in this zone for your resources will point back only to 1. If you want to create a PTR record for a server that does not reside in this network segment for example mail server which is located in 1. Add IP Address of Reverse Lookup DNS Zone. On the next screen choose to Allow only secure dynamic updates, hit next to continue and, finally hit on finish to complete zone creation. Enable Secure Dynamic Updates. New DNS Zone Summary. At this point you have a valid DNS reverse lookup zone configured for your domain. In order to add a PTR record in this zone, right click on the right plane and choose to create a PTR record for a network resource. In this case weve created a pointer for our gateway. In order to test if the record was properly added and works as expected from clients point of view, open a Command Prompt and issue a nslookup query against the name of the resource and another query for its IP Address. Both queries should return the correct answer for your DNS resource. Add DNS PTR Record and Query PTRStep 3 Domain Group Policy Management. An important aspect of a domain controller is its ability to control system resources and security from a single central point. This type of task can be easily achieved in a domain controller with the help of Domain Group Policy. Unfortunately, the only way to edit or manage group policy in a samba domain controller is through RSAT GPM console provided by Microsoft. In the below example well see how simple can be to manipulate group policy for our samba domain in order to create an interactive logon banner for our domain users. In order to access group policy console, go to Control Panel System and Security Administrative Tools and open Group Policy Management console. Expand the fields for your domain and right click on Default Domain Policy. Choose Edit from the menu and a new windows should appear. Manage Samba Domain Group Policy. On Group Policy Management Editor window go to Computer Configuration Policies Windows Settings Security settings Local Policies Security Options and a new options list should appear in the right plane. In the right plane search and edit with your custom settings following two entries presented on the below screenshot. Configure Samba Domain Group Policy. After finishing editing the two entries, close all windows, open an elevated Command prompt and force group policy to apply on your machine by issuing the below command gpupdate force. Update Samba Domain Group Policy. Finally, reboot your computer and youll see the logon banner in action when youll try to perform logon. Prince Paul A Prince Among Thieves Zip there. Samba. 4 AD Domain Controller Logon Banner. Thats all Group Policy is a very complex and sensitive subject and should be treated with maximum care by system admins. Also, be aware that group policy settings wont apply in any way to Linux systems integrated into the realm.
