Trust be­tween One­L­o­gin and ACP

To establish the trust be­tween One­L­o­gin and ACP, you need to con­fig­ure the SAML X509 certificate used for the verification of the SAML assertion.

  1. Go to OneLogin > Security > Certificates.

  2. Select Standard Strength Certificate (2048-bit) and down­load it in the X.509 PEM fro­mat.

  3. Go to ACP and paste the val­ue of the certificate un­der IDP certificate in the SAML IDP configuration view.

  4. Set Name ID for­mat as emailAd­dress.

  5. Save the SAML IDP con­figuration.


    The entity issuer attribute get generated for your IDP.

  6. Copy the val­ue of the entity issuer at­tribute from the SAML IDP view.

  7. Go to OneLogin and navigate to the Configuration view of your SAML application. Enter the copied val­ue of entity issuer at­tribute into the Audience (EntityID) field. Select Save.

  8. Navigate to the Parameters view and configure at least one assertion pa­ra­me­ter on top of NameID val­ue.


    It is required to avoid empty SAML assertions, which are not supported by ACP.
