Authentication servers
FortiGate units support the use of external authentication servers. An authentication server can provide password checking for selected FortiGate users or it can be added as a member of a FortiGate user group.
If you are going to use authentication servers, you must configure the servers before you configure FortiGate users or user groups that require them.
| MAC OS and iOS devices, including iPhones and iPads, can perform user authentication with FortiOS units using RADIUS servers, but not with LDAP or TACACS+ servers. |
