»Vault Credential Resolver
ServiceNow® MID servers can use the Vault Credential Resolver to consume secrets directly from Vault for the purpose of performing discovery. See installation and configuration for help getting started with the Vault Credential Resolver.
ServiceNow uses MID servers deployed inside customer networks to perform agent-less discovery of their infrastructure. As infrastructure such as databases or servers are discovered, their attributes such as address and software versions are stored in a database. Naturally, this process requires a wide array of credentials. Customers can use ServiceNow's built-in credential storage, or install an external credential resolver to take advantage of their existing enterprise-grade secret storage solution.
The Vault Credential Resolver is one such resolver. The MID server will not store or cache any credentials marked as external, and will invoke the credential resolver each time it requires credentials.
The Vault Credential Resolver is designed to communicate with a Vault Agent service installed on the same machine as the MID server. Authentication is handled between the Agent and Vault, and Vault Agent also handles caching and renewing leased secrets to ensure the load on Vault is minimized.
The following features are supported by the Vault Credential Resolver:
- KV, Active Directory and AWS secret engines.
- Communication with Vault via Vault Agent.
- TLS communication with Vault Agent.
