Како се исправља

Метод исправке: Смерница или закрпа инфраструктуре

Based on the Audit Procedure output, for each UID shared by more than one account, keep the UID on the correct account and assign a new, unused UID to each of the other accounts: # usermod -u <UID> <username> usermod reassigns ownership of files in the account's home directory automatically. Review any other files owned by the previously shared UID and reassign ownership to the correct account as appropriate.
