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.
Rationale:
If a group is assigned a duplicate group name, it will create and have access to files with the first GID for that group in /etc/group . Effectively, the GID is shared, which is a security problem.
Fix:
Perform the appropriate action to correct any discrepancies found.
Parameter:
[yes/no]
Technical Mechanism:
Perform the appropriate action to correct any discrepancies found.
