I did an upgrade from 4.7.6 to 4.8.0, I't broke perms, didn't notice it right away, just some app wouldn't start due to perm issue.
I allready tried the undoguidindex with no luck so I waited until 4.8.2 and trie dit instead (didn't worked)

As backup stands, there was a lack of config of my part.....
Is the following step the good way to try to restore ?

Stop samba 4.8.2
LDBDump database into a file
Drop the old database file
LDBadd file into a new database.
Run sambaundoguidindex
Start samba 4.8.2
Run samba-tool dbcheck --reindex
