Understanding MS agents

MS agents are installed on AD servers for use in certificate discovery and enrollment.

SCM uses MS agents to do the following:

  • Discover Certificates — An agent installed on a domain joined Windows server can discover assets such as web servers, domains, and certificates in Active Directory.

  • Proxy MS Enrollment Protocols to SCM — An agent installed on a domain joined Windows server can act as a proxy to issue private and public certificates by using MS AD certificate templates mapped to SCM certificate profiles.

As a redundancy measure, SCM enables you to create clusters of MS agents installed on different servers to act as a single agent. If any agent fails, the other agents in the cluster seamlessly continue certificate discovery and enrollment.

MS agents can be managed on the Integrations  MS Agents page.

MS Agents page

The following table describes the settings and controls of the MS Agents page.

Column Description

Name

The name of the agent.

Active

Indicates whether the agent is active.

Connected Nodes

For clustered agents, the number of nodes in the cluster, and the number of nodes that are currently connected.

Status

The current connection status of the agent.

The valid values are:

  • Connected — The agent is communicating with SCM.

  • Disconnected — the agent is not communicating with SCM.

  • Degraded - not all nodes of a cluster are connected.

  • Pending — Initial connection after install has not occurred.

Version

The version number of the installed agent software.

CA Proxy

Indicates whether the agent was installed with Proxy MS Enrollment Protocols to SCM enabled.
