Configuring a Certificate or Smart Card Adapter for Use with Directories Management
You can configure x509 certificate authentication to allow clients to authenticate with certificates on their
desktop and mobile devices or to use a smart card adapter for authentication. Certificate-based
authentication is based on what the user has (the private key or smart card), and what the person knows
(the password to the private key or the smart-card PIN.) An X.509 certificate uses the public key
infrastructure (PKI) standard to verify that a public key contained within the certificate belongs to the user.
With smart card authentication, users connect the smart card with the computer and enter a PIN.
The smart card certificates are copied to the local certificate store on the user's computer. The certificates
in the local certificate store are available to all the browsers running on this user's computer, with some
exceptions, and therefore, are available to a Directories Management instance in the browser.

Using User Principal Name for Certificate Authentication
You can use certificate mapping in Active Directory. Certificate and smart card logins uses the user
principal name (UPN) from Active Directory to validate user accounts. The Active Directory accounts
of users attempting to authenticate in the Directories Management service must have a valid UPN
that corresponds to the UPN in the certificate.
n
Certificate Authority Required for Authentication
To enable logging in using certificate authentication, root certificates and intermediate certificates
must be uploaded to the Directories Management.
n
Using Certificate Revocation Checking
You can configure certificate revocation checking to prevent users who have their user certificates
revoked from authenticating. Certificates are often revoked when a user leaves an organization,
loses a smart card, or moves from one department to another.

Configure Certificate Authentication for Directories Management
You enable and configure certificate authentication from the vRealize Automation administration
console Directories Management feature.
