Issue after active directory broke . Can't find my document

Hello, i use nexcloud istance with active directory user authentication.
This Active directory some day ago, break, i reinstalled it. create the same user, same active directory ip, same user credential.
When i login i don’t find any old document … how to get this back?

Solved by myself, i write here the step, if someone go wrong like me.
Since AD user are identified by SID is impossible to get back user login.

  1. Install plugin impersonate
  2. impersonate the lost in space user
  3. download file
  4. Put them back ( example via webdav ) with the “new” user


PS: Transfer Ownership is also good ( impersonating other user )
