Configure single sign-on using ADFS

This feature is only available on our Enterprise plan. Contact sales for more information. 

Before you begin, make sure you have an Admin account (Viewer or Contributor) with Abstract.

Step 1: Configure SAML 2.0 for Abstract in ADFS

Abstract supports SAML 2.0 protocol. You may need to add the following information in ADFS:



Abstract's EntityId

Abstract's Assertion Consumer Service (ACS) URL

Audience Restriction

About SAML responses:

  • We currently only support HTTP:POST binding.
  • We are expecting an "email" Assertion Attribute, as shown below.

<saml2:Attribute Name="email" NameFormat="urn:oasis:names:tc:SAML:2.0:attrname-format:unspecified">

    <saml2:AttributeValue xmlns:xs="" xmlns:xsi="" xsi:type="xs:string"></saml2:AttributeValue>


Set an attribute with Name to “email” and the value to the user’s email address (shown in screenshots below).


Additionally, make sure the "XML declaration" tag is present at the very beginning of the XML metadata:

<?xml version="1.0" encoding="UTF-8"?>

If there is no Name ID element in SAMLResponse, you receive an error.

Step 2: Set up SAML single sign-on in Abstract.

  1. Open the Abstract app (desktop or web).
  2. In the left side pane, click on the organization name.
  3. Select the Permissions tab.
  4. In the Configure SSO section, enter your Metadata URL and Entity ID.
  5. Enter any manual exceptions you might have. Emails listed in the manual exceptions section bypass SSO and can log in with email and password.
  6. Click Test with my Account. If the test fails, contact our support team to manually enable SSO.
  7. Toggle Activate SSO on. 
  8. Click Save Changes.
