If important documents are needed, please back them up locally beforehand.
The entire process can take up to 2-3 days, since all permissions on all files and directories must be reset. Initially, only the respective administrators will have access to the network drives they manage.
The home directories will probably be available again immediately after the changeover, but with the new user password.
Note: When connecting to a network drive you have to use ADDS (instead of AD) as domain.
Update (03.03.2023)
The initial permissions are reset and the basic access to the network drives is enabled again. The administrators of the respective drives can now reset the permissions for the users.
If you still cannot access your data, please contact the administrators of the network drive for which you are missing access.
