Do you know the location of the user profile? That’s a directory named user containing some subdirectories and lots(?) of files. For versions >=4.0 you should find it as ...\4\user (standard installation). I don’t know Linux specifics.
If you copy the complete \4\user range of the “master” user, and paste it to the respective location of each “slave” user, this should do.
Never overwrite a user profile without having created a backup. You can create such a backup, e.g. by simply renaming the found “slave” user folder from \user to \user.bak. If one of the afflicted users has personal basic code or templates or … they can copy the respective folder from the backup profile to the new one, overwriting what they got from the “master”.
Don’t disregard the hint by @Zizi64.
