SAML (Security Assertion Markup Language) is an open standard for authentication and authorization between a service provider and an identity provider and is commonly used to implement a single sign-on (SSO) service. By using this SSO service, there is no need to type in credentials or to remember passwords.
- Authentication - The service provider agrees to trust the identity provider to authenticate users.
- Authorization - Upon request, the identity provider generates an authentication assertion. This means that the user has been successfully authenticated and the service provider can grant the user access to certain systems or content.
Some of the identity providers supported by Devo are Google, Okta and OneLogin. Suppose a user is logged into one of these identity providers and wants to log into Devo, which operates as the service provider. Here's what happens:
- The user accesses Devo and the application loads. Devo redirects the user back to the identity provider and asks for authentication.
- The identity provider generates the authentication assertion as an XML-document containing the user’s email address, signs it using an X.509 certificate, and posts this information to Devo.
- Devo, which already trusts the identity provider and has a certificate fingerprint, receives the authentication assertion and validates it using the certificate fingerprint.
- The identity of the user is established and the user is provided with access to Devo.
Here is how an Admin enables SAML for a domain:
Enable Devo as a service provider
- Go to Preferences → Account preferences → Authentication.
- Select the SAML2 tab and check the Active box. The service provider Home URL, ACS URL, and Entity ID are automatically filled in.
- Select the Update button.
Enable the identity provider
