+Specifies whether to remove domain from user name during local user authentication (e.g., &quot;[email protected]&quot; –> &quot;user&quot;).
+This practice can be beneficial for maintaining compatibility with older versions of Kerberos.
+However, enabling this option can have negative consequences.
+It may result in confusion between domain and local users with identical names, potentially leading
+to incorrect assignment of user permissions and unintentional permission escalation,
+thus creating a security risk. Therefore, it is advisable to avoid using this option in most cases.
