Solution | GUI and CLI behavior. When attempting to create an administrative profile using the name 'admin_no_access' via the GUI, an error 'A duplicate entry has already existed' is displayed because the name is reserved by the system. The profile 'admin_no_access' is not visible in the GUI.
  PRO # config system accprofilenPRO (accprofile) # edit admin_no_accessnThis entry is reserved by system. Cannot be edited.nCommand fail. Permission denied
     Reserved profiles. Are hidden from the GUI. Cannot be modified or edited via CLI. Are protected to prevent conflicts with internal system operations. To achieve similar functionality, a new access profile should be created using a unique, non-reserved name, e.g., AdminNo_access, AdminsProfile, etc.
 Conclusion:
Avoid using the reserved name ‘admin_no_access’ when creating custom administrative profiles, as it is reserved by the FortiWeb system. Use a unique profile name to ensure proper management and prevent conflicts. Reserved profiles cannot be viewed, edited, or deleted.  Related document: Configuring access profiles |
