1. Login Nuxeo Platform as User02 account.
2. Create a folder "share" in User02.
3. Create another folder "parent" and inside "parent" folder, create a child folder "share".
4. Share the folders share and parent/share to User01 with permission Everything.
5. Drive: Login as User01 and wait for sync completion.
   Confirm the downloaded folders are share and share__1.
6. Drive: navigate to settings->Accounts tab and Delete account.
7. After successful disconnection, connect again User01 account with same Folder location.
   Location: C:\Users\<user name>\Documents\Nuxeo Drive
