Once registered with the certificate service your authorised users can sign in using the institutional login. This page will help you set up OpenAthens to enable that - for instructions about using the Sectigo Certificate Manager, please see

As with all other resources, we don't know anything about the internal workings of the certificate manager service and can only help you with setting up the attributes and related release policy we've been told it requires.


  • You will need domain / owner level access to the OpenAthens admin area
  • If you use restrictive mode you will need to add this resource to the permission set(s) used by the users you have authorised on the service - you may prefer to create one specifically for those few users and this resource.
  • You will need to be able to release some attributes that you would not usually release, such as an email address, so relevant users must have data in those fields 


  1. Go to Preferences > Attribute release
  2. Click the 'Add a resource policy’ button and search for "Sectigo Certificate Manager"
  3. Click on the attributes you want to release - the ones representing emailAddress and EPPN, and optionally First name and Last name
  4. Unless you have created them in the schema editor to have the required attribute names you will need to click on advanced and go to the attribute aliases section to release them with the expected names:
    1. In the left hand box select the orginal target name (e.g. emailAddress)
    2. In the right hand box enter the desired target name from the list above (e.g. urn:oid:0.9.2342.19200300.100.1.3)
  5. When you've set them all up click on Done and then Save at the top of the page


You can test at


  • I mapped an attribute but it's not releasable
    • Either you have not set the schema attribute as releasable in the schema editor or you have not correctly mapped your local attribute to the schema attribute. 
      • The schema attribute must exist before you set up the mapping
      • Attribute names are case sensitive
  • I get a denied message from the certificate manager or test page
    • Either you are not registered with them yet or you are not releasing the required attributes
      • If attributes... check the account has values against the relevant fields, and if it does check the attribute aliases for typos in the release policy (advanced section)
  • I get a denied message from OpenAthens
    • If the message is from us then you probably have restrictive mode enabled and have not added the "Sectigo Certificate Manager" to the permission set used by the account
