Behebungsmethode: Anleitung oder Infrastruktur-Patch
Based on the Audit Procedure output, for each duplicated group name, determine which entry is correct and make each group name unique. Use vigr to safely edit the group database and either remove the redundant entry or rename it to a unique group name: # vigr File group ownerships will reflect the change automatically as long as each group has a unique GID.
