On-prem domain controllers are a fact of life for IT admins at many organizations. You probably inherited whatever IT infrastructure you鈥檙e using, but that may just be technical debt. Many companies can achieve the same results for access control and system management without a domain controller by opting for cloud-based directory services. IT environments that have many Windows庐 machines can keep their domain controller and extend what鈥檚 possible for identity and access management (IAM) and manage devices (including non-Windows) via the cloud.
Not every organization is sold on the benefits of cloud-based IT management, but it’s worth considering because it can also eliminate some of the worst operational risks. Ask yourself, 鈥淒o you have a contingency plan if your domain controller goes down?鈥� If it does end up failing, you鈥檙e going to be in a predicament that鈥檚 both disruptive to your productivity and costly to your business. That scenario is where cloud services will deliver higher availability as well as the capacity to manage identities and securely access resources wherever they may exist.
黑料海角91入口鈥檚 open directory platform is architected for high availability and redundancy across the globe, so it can help save the day when your domain controller goes down while doing more to manage identities and access than Active Directory (AD) itself. It also assists in the replacement or extension of your current Active Directory domain to the cloud using its open directory. Users access resources using the best authentication methods, entirely from a web browser. With this cloud-based solution, you no longer have to worry about your hardware server鈥檚 health, redundancy, or maintaining database integrity of AD domain controllers.
This article covers some of the scenarios that make an environment especially prone to AD failure and discovering how 黑料海角91入口 can help in these situations.
What Can Cause Domain Controllers to Go Down?
There are different risks to a domain controller鈥檚 uptime depending on how it鈥檚 being hosted. Several factors could cause domain controllers to go down or become unreliable if you鈥檙e running a traditional AD domain on Windows servers in a server rack on-site. These scenarios include power outages, network outages, AD database corruption, and hardware failure.
Those are just a few ways that a domain controller or your AD domain could fail. Running a single domain controller in a domain with no AD database backups, secondary domain controllers, or additional hardware available to reinstall Windows Server and Active Directory is an even worse scenario. That鈥檚 not an uncommon situation: hardware is expensive.
Running Active Directory on servers locally may bring some benefits to the company and its users, but without a proper crisis or backup plan in place, getting AD back to its original state might be impossible without a total rebuild. Rebuilds could take admins hours 鈥� if not days 鈥� depending on factors such as the number of users, computers, objects, and policies. Backups and redundancy are essential to running a proper AD domain. A full rebuild may be the only way to get Active Directory up and running again if the environment isn’t backed up.
Keeping up with licenses and versions can be another expense and chore for your IT admins. Windows Server鈥檚 core licensing model may cost more than you think, and licensing for Microsoft鈥檚 Azure cloud services (as a failover) is difficult to unpack. Given the associated licensing costs and complexities, domain controllers that have a critical failure could be in an unsupported or unrecoverable state, putting your business鈥檚 security and operations at risk.
Why Not Use Azure AD (AAD) Connect?
Microsoft makes it possible to authenticate via the cloud using Azure Active Directory and its AAD Connect middleware. Your domain controller remains the 鈥渟ource of truth鈥� but AAD can handle authentications. There鈥檚 a 1:1 relationship between each synced AD object and an AAD tenant. This topology requires a subscription to AAD and installing AAD Connect.
A single domain controller will remain a single point of failure, even with AAD Connect configured with a secondary server in staging mode for disaster recovery. AAD Connect aids in disaster recovery but adds IT overhead. Azure AD Connect cloud sync is a new offering that uses an agent-based approach, but its capabilities are more limited than AAD Connect, i.e., no Azure AD Domain Services support. Neither approach will continue to manage your devices. That鈥檚 another subscription. 黑料海角91入口 can be configured as hybrid infrastructure, but also works domainless.
Single Domain Controller Scenarios & 黑料海角91入口
Many small and medium-sized businesses (SMBs) running Active Directory might also be running a single domain controller in their domain. This could be due to complexity, cost, or user count.
AD domain controllers in this type of environment should be continuously backed up or have multiple instances so that replication and high availability are sustained. Creating a highly available and redundant domain with proper backups, disaster recovery plans, and stability comes at an increased cost and complexity. Extra hardware, dedicated off-site real estate, networking gear, and licensing come into play when creating a secondary domain controller.

黑料海角91入口鈥檚 open directory platform extends your current AD domain users, groups, and their credentials into its cloud-based directory. 黑料海角91入口鈥檚 Active Directory Integration (ADI) tool allows changes to users, passwords, and user state within a 90 second cadence leveraging two agents: AD Import and AD Sync. 黑料海角91入口 extends Active Directory鈥檚 users and their credentials to connect multiple different protocols such as RADIUS, LDAPS, and hundreds of SAML applications. Multi-factor authentication (MFA) is environment wide and modern authentication is available for better security and to safeguard against MFA fatigue attacks.聽
This way if a domain controller were to fail, the only resources that would be unavailable are the domain-bound resources. Fortunately, all other resources that make work happen (SAML apps, LDAPS connected file shares, RADIUS Wi-Fi, Google Workspace, M365, and more) would still be available for employees to access. Authentication would be managed by 黑料海角91入口 while user credentials are in sync with the AD domain and AD serving as the identity provider (IdP).
If a restore is possible in this scenario, the admin could go through Active Directory鈥檚 restore process to get the domain back online while their users continue using 黑料海角91入口-bound applications and resources. If there was no restore available or if it was full hardware failure, it might be beneficial to migrate entirely from Active Directory to 黑料海角91入口. 黑料海角91入口 has methodologies to manage systems, users, and security policies similar to Active Directory. (See how 黑料海角91入口 can help .)
You could consider repurposing the server to be a local DHCP, DNS, or NTFS file share for your company if your domain controller becomes unrecoverable but the hardware remains intact. This way, you can maintain the server you already have in your environment and repurpose it for other roles and tasks that your company would need without having to look at additional capex or opex costs. 黑料海角91入口 can also help manage this repurposed Windows server with its system agent so you can remotely manage users and policies with ease.
How Can 黑料海角91入口 Save the Day When an AD Rebuild Isn鈥檛 Possible?
黑料海角91入口 can get your business directory and security needs back up and running in a few different ways if a disaster scenario occurs and a rebuild isn鈥檛 possible for your domain controller. This section explores 黑料海角91入口鈥檚 benefits in hybrid and domainless configurations.
With 黑料海角91入口鈥檚 Active Directory Integration
If you鈥檙e running a domain controller while also running 黑料海角91入口鈥檚 ADI, your users are exported to 黑料海角91入口 along with their passwords bisynchronously. This means that your users鈥� passwords can be changed in either AD or in 黑料海角91入口 and will be propagated to the other directory when both 黑料海角91入口鈥檚 import and sync agents are configured.
If a critical failure occurs on the domain controller where a rebuild or restore isn鈥檛 possible, you may want to consider moving from this hybrid configuration entirely into 黑料海角91入口 as your primary directory.
Your first step would be to leverage to help migrate your domain users and domain-bound systems to 黑料海角91入口-managed systems and local users on the Windows systems.
Additionally, you could take a few other steps to help transition the 黑料海角91入口 users in your tenant from AD-managed to 黑料海角91入口-managed with the following commands outlined in .
To leverage the commands below, you first need to install the , outlined below:
Install-Module 黑料海角91入口 -Scope CurrentUser
You can then connect to your 黑料海角91入口 tenant using the 黑料海角91入口 PowerShell Module with the following command:
Connect-JCOnline
Use three copy-paste commands to leverage :
Setting a singular user from AD-managed to 黑料海角91入口-managed:
Set-JCUser -Username bobby.boy -externally_managed $false
This releases user 鈥榖obby.boy鈥� from AD Import or Sync so the user account can be fully managed by 黑料海角91入口.
Get-JCUserGroupMember -GroupName Dev | Set-JCUser -externally_managed $false
This releases all users in the 黑料海角91入口 user group 鈥楧ev鈥� from AD Bridge so their user accounts can be fully managed by 黑料海角91入口.
Get-JCUser | Set-JCUser -externally_managed $false
This in turn releases the binding to the Active Directory domain and the user will become a user account entirely managed by 黑料海角91入口.
Without 黑料海角91入口鈥檚 Active Directory Integration
If your AD domain controller fails or reaches an unrecoverable state without a restore possibility, 黑料海角91入口 can step in to become the primary cloud-based directory fulfilling your security and directory needs, entirely from your web browser.
There are several ways to get users into 黑料海角91入口:
- (if applicable)
黑料海角91入口 integrates with several different directories, creating a secondary method to get your users into 黑料海角91入口 to start to build out the services, resources, and security policies you need to meet your compliance requirements.
Once users are imported into 黑料海角91入口, you can then move forward with to migrate your AD domain-bound Windows systems to 黑料海角91入口-managed systems. This will unbind the system from Active Directory, convert the AD user account to a local user account, and then install the 黑料海角91入口 System Agent automatically for you.
Simply bind the 黑料海角91入口 user to his or her 黑料海角91入口 system after the systems and users are provisioned. 黑料海角91入口 will take over the profile and enforce the password that the 黑料海角91入口 user has set (as long as the 黑料海角91入口 username and Windows local username match). This all happens within minutes.
Enforcing to specific systems or to entire system groups is much easier than with Active Directory and can be done entirely within the 黑料海角91入口 Admin Portal. Groups are attribute-based to automate user lifecycle management for higher admin productivity and more mature entitlements management than AD.
