Describe the bug

During the test upgrade of the 2025.12.0-rc1 I faced an issue in my setup, where I have more than 1 group with the same name that came from two different LDAP Sources.

Seems the changes on #17050

Have introduced a unique index in the name on authentik/core/migrations/0056_user_roles.py

migrations.AlterField(
            model_name="group",
            name="name",
            field=models.TextField(unique=True, verbose_name="name"),
        ),

How to reproduce

1. Have equal Group Names on version 2025.10.0
2. Do the Upgrade to version 2025.12.0

Expected behavior

Groups, I do not see the need for a different name, especially if they are Nested Groups. For example, I have root Groups as Departments, with a similar structure under each.

• Department A
  - Manager
  - Team
• Department B
  - Manager
  - Team
