CyberArk states that users can authenticate to the Vault through PSM for SSH using:
* CyberArk password authentication (i.e., CyberArk authentication),
* LDAP, and
* RADIUS (including challenge-response).
Windows, SAML, and OIDC are not listed as direct PSM for SSH authentication methods in the PSM for SSH authentication configuration (Privilege Cloud / PSM for SSH uses the configured PSM for SSH authentication methods such as Password/LDAP/RADIUS)
