Azure Active Directory Synchronize on-premises directories and enable single sign-on; Azure Active Directory B2C Consumer identity and access management in the cloud; Azure Active Directory Domain Services Join Azure virtual machines to a domain without domain controllers The server app never started. The server app started. However, there was a failure during initialization that prevented the server app from registering with the RPC Endpoint Mapper. The server app started but later died. The server app manually unregistered its endpoints. (This resembled the previous cause, but its occurrence was intentional. Active Directory is just one example of a directory service that supports LDAP. There are other flavors, too: Red Hat Directory Service, OpenLDAP, Apache Directory Server, and more. LDAP vs. Active Directory. LDAP is a way of speaking to Active Directory. Note: macOS Sierra and later can't join an Active Directory domain without a domain functional level of at least Windows Server 2008, unless you explicitly enable "weak crypto."Even if the domain functional levels of all domains are 2008 or later, the administrator may need to explicitly specify each domain trust to use Kerberos AES encryption. In Active Directory deployment, the only computer configured with a time server explicitly should be computer holding the PDC Emulator FSMO role in the forest root domain. This is because the Forest root domain PDC emulator is the one and only one-time source for all the Domain Controllers, member servers and windows based workstations for the After a restore in Directory Services Restore mode, the domain controller should be restarted in normal mode. When the directory service starts, the domain controller will perform the normal consistency check and the restored directory will then be online. Be aware that restoring an Active Directory server is always a two-part operation.

Creating the Active Directory After you have installed Windows Server 2003 on a stand-alone server, run the Active Directory Wizard to create the new Active Directory forest or domain, and then convert the Windows Server 2003 computer into the first domain controller in the forest.

Pricing details. Azure Active Directory comes in four editions—Free, Office 365 apps, Premium P1, and Premium P2. The Free edition is included with a subscription of a commercial online service, e.g. Azure, Dynamics 365, Intune, and Power Platform. Active Directory Federation Services (AD FS), a software component developed by Microsoft, can run on Windows Server operating systems to provide users with single sign-on access to systems and applications located across organizational boundaries. It uses a claims-based access-control authorization model to maintain application security and to implement federated identity.

Active Directory server. Using Microsoft Active Directory, you can register the firewall as a Windows domain and create an object for it on the primary domain controller. The firewall can then query user and resource information on the Windows domain network.

After a restore in Directory Services Restore mode, the domain controller should be restarted in normal mode. When the directory service starts, the domain controller will perform the normal consistency check and the restored directory will then be online. Be aware that restoring an Active Directory server is always a two-part operation. The Active Directory (AD) is a directory service included in the Microsoft Windows Server 2008 operating system. The Active Directory acts as a central hub from which network administrators can perform a variety of tasks related to network management.
