I have upgraded Nintex Automation K2 from version 5.6 → 5.8 → 5.9.

The upgrade completed successfully without any errors.
The web site is running normally, and users can:

  • Create SmartForms

  • Run workflows successfully

However, I found an issue after the upgrade:

When I try to log in with some test users (for example: k2test1), they cannot access the Workspace page
(e.g. https://k2test.xxxxx.com/workspace).

The following error message is displayed:

 

Not authorized
You do not have permission to view the page that you have requested.
The administrator of this SmartForms environment has restricted access to this page.
If you believe that you should have access to this page, please contact your SmartForms administrator.


 

Important details:

  • k2test1 is a normal user (no special permissions)

  • Before upgrading to K2 5.9, this user could access Workspace normally

  • After testing multiple users, I found that:

    • Some users get "Not authorized"

    • Some users can access Workspace without any issue

  • No configuration was intentionally changed regarding user permissions

Question:

What could be the cause of this issue after upgrading to K2 5.9?
Are there any permission changes, SmartForms security settings, or post-upgrade steps that I should check or reconfigure to resolve this problem?

Good day,

Do you use Active Directory or Azure Active Directory?

We are using Active Directory.
User k2test1 can access Production (v5.6), but cannot log in to the Test environment after upgrading to v5.9.
This issue does not affect all users.
