Samba4 primaryGroupID problem

[Alexis]

Hi,
I was reading this "old" post about db corruption when changing 
primaryGroupID via ldbedit:

>> ERROR: orphaned backlink attribute 'memberOf' in CN=bar,OU=Domain
>> Users,DC=X for link member in CN=bargroup,OU=Domain Groups,DC=X
>> Not removing orphaned backlink member
>> ERROR: incorrect DN string component for member in object
>> CN=bargroup,OU=Domain Groups,DC=X -
>> <GUID=762c38c2-f7c7-4915-87f0-bf189abb553e>;CN=bar,OU=Domain Users,DC=X
>> Not fixing incorrect string version of DN

As I have the exacte same problem with 4.0.4 version I was wondering what 
could be done to have this solved.
