Add enterprise SSO to Windows Server 2019 RDP sessions. Authenticate via your corporate IdP instead of AD passwords. Deploy with local agent or gateway RDP proxy for agentless coverage.
Identity-Based RDP Access for Windows Server 2019
Windows Server 2019 remains one of the most widely deployed server operating systems in enterprise environments, running critical workloads from Active Directory and DNS to SQL Server, Exchange, and line-of-business applications. Its mainstream support ended in January 2024, meaning it now receives only security updates — yet millions of instances continue running in production. RDP authentication on Server 2019 still relies on AD credentials via NLA, offering no native path to SAML/OIDC SSO or centralized MFA from non-Microsoft identity providers. OnePAM solves this by providing two deployment options. The local agent installs on each Windows Server 2019 instance and intercepts the RDP credential provider flow, redirecting authentication to your corporate IdP (Okta, Azure AD, Google Workspace) before granting desktop access. The gateway RDP proxy operates as a dedicated OnePAM instance that authenticates users via SAML/OIDC and then brokers the RDP connection to the target server — no agent installation required. Both approaches deliver MFA enforcement, session recording, and compliance-ready audit trails.
Local Agent
Install the OnePAM agent on each Windows server. The agent intercepts RDP authentication and enforces SAML/OIDC SSO with Kerberos and Protected User support before granting desktop access — no gateway required.
Gateway RDP Proxy
Run a dedicated OnePAM gateway with native RDP protocol support. Users authenticate via SAML/OIDC at the gateway, which brokers the RDP session using Kerberos NLA. No agent needed on target servers.
RDP Security Risks on Windows Server 2019
Without identity-based RDP access, these risks threaten your Windows servers every day.
RDP Security Challenges
These are the risks organizations face with traditional RDP authentication.
AD Password Dependency
RDP on Server 2019 requires Active Directory passwords. Organizations cannot enforce SAML/OIDC SSO from Okta, Google Workspace, or other non-Microsoft IdPs. OnePAM bridges this with native Kerberos authentication combined with SAML/OIDC SSO.
Extended Support Phase
Server 2019 mainstream support ended in January 2024. Security-only updates mean fewer protections against emerging RDP attack techniques.
NTLM Fallback Risk
Without Kerberos enforcement and Protected User group support, RDP connections can fall back to NTLM, exposing credentials to relay and pass-the-hash attacks.
Ransomware Target
RDP-exposed Windows Server 2019 instances are the primary entry point for ransomware groups using brute-force and stolen credentials.
No Built-In Session Recording
Windows Server 2019 does not provide native RDP session recording. Event logs capture login events but not session activity.
Lateral Movement Risk
Once an attacker compromises one server via RDP, they use the same AD credentials to move laterally. Kerberos with Protected User enforcement and short-lived tokens breaks this chain.
How OnePAM Adds SSO to Windows Server 2019 RDP
Step-by-step guide to deploying identity-based Windows RDP access.
Choose Agent or Gateway Mode
Install the OnePAM agent on Server 2019 for direct SSO, or deploy a gateway RDP proxy for zero-install protection.
Connect Your Corporate IdP
Configure your SAML 2.0 or OIDC identity provider — Okta, Azure AD, Google Workspace, Ping Identity, or any compliant provider.
Map Users to Windows Accounts
Define mappings between IdP identities and Windows user accounts (local or domain) for RDP session creation.
Set Access Policies
Create granular policies: who can RDP into which servers, with what MFA, from which locations, during which hours.
Monitor and Record
Audit every RDP session with identity context. Enable visual session recording for compliance and incident response.
Business Impact of SSO for Windows Server 2019 RDP
Measurable security and operational outcomes from deploying OnePAM Windows RDP SSO.
Kerberos NLA with Protected User
OnePAM authenticates to Server 2019 via Kerberos NLA with Protected User group enforcement, blocking NTLM downgrade and credential theft attacks.
Kerberos + Protected UserBlock Ransomware Initial Access
RDP brute-force and credential stuffing attacks fail because OnePAM requires IdP-verified authentication — no passwords to spray.

As Server 2019 enters extended support, OnePAM provides a compensating control layer with native RDP protocol handling that shields from new vulnerabilities.
