說明

Although the groupadd program will not let you create a duplicate group name, it is possible for an administrator to manually edit the /etc/group file and change the group name.

修補方式

修補方法: 操作指南或基礎設施修補檔

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.
