Administrator Fornetet is able to view logs and perform device management tasks such as adding and removing registered devices, but cannot create a mail server to send alert mails. The causes of this problem are:
fortinet is assigned a Restricted_User administrative rights profile.
Administrators who are assigned as Restricted_User have restricted access, which may include viewing logs and performing certain device management tasks, but not more advanced administrative functions such as configuring mail servers. Such permission restrictions prevent them from performing configuration changes that require higher permissions.
