Looks good, works fine. I have just 2 minor styling issues:

1) The following blob can be simplified. From:

+        is_protected_group = False
+        if keys[-1] in PROTECTED_GROUPS:
+            is_protected_group = True

to:

is_protected_group = keys[-1] in PROTECTED_GROUPS


2) Lines with raised error messages are quite long:

+                raise errors.ProtectedEntryError(label=u'group', key=keys[-1],
reason=u'Cannot be renamed')

+                raise errors.ProtectedEntryError(label=u'group', key=keys[-1],
reason=u'Cannot support external non-IPA members')

They should be wrapped.
