To set up SAML using the raw Metadata XML file, follow the steps below:

1. Open the copied Metadata URL in a browser tab and copy the XML content.
2. Navigate to Appsmith and add the raw XML in the Metadata XML field under the Register Identity Provider section in the SAML 2.0 configuration page.

IdP data

If you have Identity provider data like X509 Public Certificate, Email, you can choose this option to configure SAML.

1. Open the Metadata URL in a browser tab or open the Metadata XML file.
2. Add the following values from XML tags in IdP Data under the Register Identity Provider section in the Appsmith SAML 2.0 configuration page:

IdP Data Field	Metadata XML Tag
Entity ID	Enter the value of the entityID attribute specified in the <EntityDescriptor> tag.

Once you have added the details, click the SAVE & RESTART button to save the configuration and restart the instance.

After the Appsmith instance restarts, try logging in again to your account. You'll see a login screen with the SIGN IN WITH SAML SSO button.
