Specifically, in this scenario involving Microsoft Active Directory, the following error message will be displayed upon logging in:

To address this issue, follow these steps:

  1. Navigate to the Administration section.
  2. Click on External Identity Sources.

After clicking on “External Identity Sources,” you will be presented with a list of all the external sources. In this specific case, Active Directory will be listed, along with the associated domain. To proceed, select the domain and click on the “Groups” option located on the right-hand side.

Once you have highlighted the “Groups” option, proceed to click on “Update SID Values.” This action will update the group membership within Active Directory (AD).

Once the values have been successfully updated, you should be all set with the new group. Give it a try now, and it should work without any issues.
