Accellion (SP-initiated) Integration Guide


Use this guide to enable Multi-Factor Authentication and Single Sign-on (SSO) access via SAML to Accellion.


1. Have an Accellion account

2. Create a New Realm for the Accellion integration

3. Configure the following tabs in the Web Admin before configuring the Post Authentication tab:

  • Overview – the description of the realm and SMTP connections must be defined

  • Data – an enterprise directory must be integrated with SecureAuth IdP

  • Workflow – the way in which users will access this application must be defined

  • Multi-Factor Methods – the Multi-Factor Authentication methods that will be used to access this page (if any) must be defined

SecureAuth IdP Configuration Steps



1. In the Profile Fields section, map the directory field that contains the user's Accellion ID to the SecureAuth IdP Property

For example, add the Accellion ID Field to the Email 2 Property if it is not already contained somewhere else


Click Save once the configurations have been completed and before leaving the Data page to avoid losing changes

Post Authentication


2. Select SAML 2.0 (SP Initiated) Assertion Page from the Authenticated User Redirect dropdown in the Post Authentication tab in the Web Admin

3. An unalterable URL will be auto-populated in the Redirect To field, which will append to the domain name and realm number in the address bar (Authorized/SAML20SPInit.aspx)

4. A customized post authentication page can be uploaded, but it is not required

User ID Mapping


5. Select the SecureAuth IdP Property that corresponds to the directory field that contains the Accellion ID (Email 2)

6. Select urn:oasis:names:tc:SAML:1.1:nameid-format:unspecified from the Name ID Format dropdown (default)

Select a different option if Accellion requires it, which the Service Provider (SP) will provide

7. Select False from the Encode to Base64 dropdown

SAML Assertion / WS Federation


8. Set the WSFed/SAML Issuer to a Unique Name that will be shared with Accellion

The WSFed/SAML Issuer must match exactly on the SecureAuth IdP side and the Accellion side

9. Set the SAML Audience to https://myaccellion.<company>.com/simplesaml/module.php/saml/sp/metadata.php/default-sp/1000

10. Provide the SP Start URL to enable SSO and to redirect users appropriately to access Accellion

For example, the SP Start URL would be

11. Set the SAML Offset Minutes to make up for time differences between devices

12. Set the SAML Valid Hours to limit for how long the SAML assertion is valid


No configuration is required for the WSFed Reply To/SAML Target URL, SAML Consumer URL, or SAML Recipient fields


13. Leave the Signing Cert Serial Number as the default value, unless there is a third-party certificate being used for the SAML assertion

If using a third-party certificate, click Select Certificate and choose the appropriate certificate

Accellion requires certificates to be in PEM format, so a conversion will be required before sending it to the SP

14. Provide the Domain in order to Download the Metadata File to send to Accellion (if required)


Click Save once the configurations have been completed and before leaving the Post Authentication page to avoid losing changes

Forms Auth / SSO Token

Optionally, in the Forms Auth / SSO Token section, click the View and Configure FormsAuth keys/SSO token link to configure the token/cookie settings and configure this realm for SSO.


Accellion Configuration Steps


1. Log into the Accellion Manager console

2. Click Administration, then SSO

3. Click Edit and then configure the settings as followed:

  • Protocol: = SAML 2.0

  • E-Mail Attribute: = mail

  • Entity ID = The Issuer Unique Name that was set in the Web Admin, which must match exactly here

  • Single Sign-On Service URL = The SecureAuth IdP realm for Accellion (e.g.

  • Single Logout Service URL = The URL on which users will land upon signing out

  • RSA Public Key Certificate: = Click choose to upload the Certificate and use the Sign Cert Serial Number from the SecureAuth IdP Web Admin

4. Click Submit
