Foundations in Access & Grouping - Thursday, June 6 @ 12:15 - 1:00 pm ET

Join this session for an exploration of Access & Grouping in higher education, where we unpack the business concept and practical applications. Learn key terms such as access, groups, and roles, and discover basic and complex workflows for managing access permissions and group memberships. Gain insights into different access architectures and real-world examples of implementation within universities.

Learning Objectives for the Attendees:

1) Understand access & grouping in context of the reference architecture + key terms including roles, role-based access, and attribute-based access

2) See basic workflows for adding individuals to groups in higher education settings, highlighting membership management processes.

3) Understand how to navigate more complex workflows involving group calculations, demonstrating advanced access management techniques.

4) See/understand basic access architectures commonly found in higher ed, providing context for implementing access and grouping concepts effectively

5) Get insights into grouping and authorization strategies in a hybrid cloud environment (e.g. local directory + Azure/AWS/GCP)

Grouper Training is ongoing this week (March 12-15, 2024)

Current Work


  • Rules screen is done
  •    Vivek and Chris will work together on rules screens to finalize

  • Chad found issue w Grouper provisioner, now fixed
    •    If not selecting all groups and entities from a membership object provisioner (google) and someone added a user or membership at target, Grouper was not able to  link back to the right group
    • Now working on deleting folders should also delete rules, this is in progress (when deleting groups/folders, check for rules, and let user know, and delete those rules too)



  • Chris and Chad working on Grouper Training, happening this week
  • Two new training modules on ABAC  are being presented 
  • Hope to go thru read only / view only sysadmin groups to be sure they have access they need
  • Logging issues in v5 
  • Used to log to pipes
  • Didn’t totally switch over
