Authentication Tab

Server Admins can set or change the site authentication mechanism. This is typically completed during the initial configuration of your Alation system, however, changes can be applied at any time.

On the Authentication tab, you can configure and test the parameters for LDAP authentication and select and save the authentication type.

Alation supports the following types of authentication:

  • Built-in this is the default authentication with a login and password created by a user. Users can sign up for an account on the login screen and log in after confirming their email.

  • LDAP requires configuration. You can configure LDAP authentication on the Authentication tab, test it, select LDAP as the active authentication method. For details about LDAP configuration, see User Authentication with LDAP.

  • SAML requires configuration and cannot be configured in Alation UI. Selecting and saving this value on the Authentication tab only serves informational purposes. SAML authentication should be configured and applied using the Alation backend. For details about SAML configuration, see User Authentication with SAML.
