Microsoft Dynamics CRM supported configurations
Applies To: CRM 2015 on-prem
The deployment architecture you will use depends on your business needs. Examples are provided here for planning a Microsoft Dynamics CRM deployment on four representative computer system architectures: a single-computer server deployment, a two-server deployment, a five-server deployment, and a multiple-server deployment involving a minimum of six servers. These deployments are discussed in detail in Microsoft Dynamics CRM supported configurations.
Additionally, this section describes the supported network, domain, and server configurations for Microsoft Dynamics CRM, which supports multiple domains in either a native- or interim-mode environment.
The Active Directory requirements are as follows:
The computers that run Microsoft Dynamics CRM Server roles and the computer that runs SQL Server, where the Microsoft Dynamics CRM databases are located, must be in the same Active Directory domain.
The Active Directory domain where a Microsoft Dynamics CRM Server role is located must run in one of the domain modes listed in the Active Directory modes topic.
The user account that is used to run a Microsoft Dynamics CRM service must be in the same domain as the computer that is running the Microsoft Dynamics CRM Server role.
The Microsoft Dynamics CRM security groups (PrivUserGroup, SQLAccessGroup, ReportingGroup, and PrivReportingGroup) must be in the same domain as the computer that is running Microsoft Dynamics CRM. These security groups can be located in the same organizational unit (OU) or in different OUs. To use security groups that are located in different OUs, you must install Microsoft Dynamics CRM Server by using an XML configuration file and specify the correct distinguished name for each pre-existing security group within the <Groups> element. More information: Sample server XML configuration file for installing with pre-created groups
Warning Direct user account membership in the Microsoft Dynamics CRM privusergroup security group is required and group membership nesting under privusergroup currently is not supported. Granting membership to privusergroup through another security group can cause system-wide failures in the CRM web application and reporting features. For example, if you add a security group named mycrmprivgroupusers to privusergroup, members of mycrmprivgroupusers will not resolve as privusergroup members. This includes the CRMAppPool or the SQL Server Reporting Services service identities.
For users who access Microsoft Dynamics CRM from another domain and are not using claims-based authentication, a one-way trust must exist in which the domain where the Microsoft Dynamics CRM Server is located trusts the domain where the users are located.
Important To add users to Microsoft Dynamics CRM that are not authenticated by using claims-based authentication, a two-way forest trust is required.
For small user bases, a Microsoft Dynamics CRM Server (any edition) can be deployed in a single-server configuration, with Microsoft Dynamics CRM Server, SQL Server, Microsoft SQL Server Reporting Services, and optionally Microsoft Exchange Server installed and running on the same computer.
Single-server deployments are not recommended for best experience in application performance and disaster recovery.
There is one limitation to single-server deployments: the server where Microsoft Dynamics CRM Server is installed cannot also function as a domain controller. If the computer is a member server (not functioning as a domain controller), you can deploy the Microsoft Dynamics CRM Server Full Server role on a single Windows Server that is also running the additional required products.
|Running Microsoft Dynamics CRM Server in a production environment on an Active Directory domain controller is not supported.|
|To reduce IT administration overhead, consider running Microsoft Dynamics CRM in the cloud. More information: Microsoft Dynamics|
