Exception thrown on adding "RunAs" {user,group}

[mddeff]

When adding a user/group using sudorule_add_runasuser and "RunAsGroup" set to category=all ("Any Group" in the UI), library throws exception:
python_freeipa.exceptions.BadRequest: users cannot be added when runs user or runAs group category='all'

The inverse is also occurs; when RunAsUser is set to "Anyone" (category=all) and you try to add a RunAsGroup.

This is a valid configuration in the IPA UI.
