Re: [Samba] corrupted db after upgrading to 4.7

Hello everyone.

So i also tried to removemembers & ldbmodify/ldbedit to remove the duplicate link but unfortunately it's not working 

"objectclass_attrs: attribute 'memberOf' on entry 'CN=Gerard Vraux,OU=CPAS,OU=MUSERS,DC=contoso,DC=com" must not be modified directly, it is a linked attribute"

So even if i want to fix everything manually, i can't.

Do you have any solutions/scripts to fix the situation ?

Have a good day.

actually this last symptom was the one that got us to hack quickly a 
solution for the issue with orphaned backlink attribute 'memberOf'. 
You'll probably have to do some cleanup as I pointed out in my last mail.

The bugzilla entry [1] you mentioned and corresponding patch prevents 
the problem from happening, but I don't think it fixes it.
