As of Dynamics 365 (CRM) version 9.X, LDAPS (LDAP over SSL) is not natively supported for authentication or integration. Microsoft has moved away from LDAP/LDAPS in favor of modern authentication protocols like OAuth 2.0 and Azure Active Directory (Azure AD) for secure authentication and integration.
Dynamics 365 relies on Azure AD as its primary identity provider, which uses modern authentication protocols (e.g., SAML, OAuth 2.0) instead of LDAP/LDAPS.
LDAPS is considered legacy and less secure compared to modern standards like OAuth 2.0.
If you need to integrate with an on-premises Active Directory (AD) or other LDAP-based systems, consider the following options:
Azure AD Connect:
Sync your on-premises AD with Azure AD using Azure AD Connect.
This allows Dynamics 365 to authenticate users via Azure AD, which supports modern protocols like OAuth 2.0.
Custom Middleware:
Develop a custom middleware application (e.g., using .NET or Node.js) to act as a bridge between Dynamics 365 and your LDAP server.
The middleware can handle LDAPS queries and translate them into API calls or data updates in Dynamics 365.
Third-Party Integration Tools:
Use third-party tools like KingswaySoft or Scribe Online to integrate LDAP/LDAPS data with Dynamics 365.
These tools often provide pre-built connectors for LDAP and Dynamics 365.
Hybrid Scenarios:
If you have a hybrid environment (on-premises AD + Azure AD), leverage Azure AD for authentication and sync necessary user attributes using Azure AD Connect.
Set Up Azure AD Connect:
Install and configure Azure AD Connect to sync your on-premises AD with Azure AD.
Ensure that user attributes required by Dynamics 365 are synchronized.
Configure Dynamics 365 to Use Azure AD:
In the Dynamics 365 admin center, set Azure AD as the identity provider.
Ensure that users are licensed and mapped correctly in Azure AD.
Test Authentication:
Verify that users can log in to Dynamics 365 using their Azure AD credentials.
If you absolutely need LDAPS for specific use cases (e.g., legacy systems), you’ll need to implement a custom solution or middleware, as Dynamics 365 does not support LDAPS directly.
While Dynamics 365 CRM 9.X does not support LDAPS natively, modern alternatives like Azure AD and OAuth 2.0 provide more secure and scalable solutions. If you’re upgrading your AD infrastructure, consider moving to Azure AD for seamless integration with Dynamics 365
