No SMS MFA with FAC as LDAP server

FortiToken Cloud (FTC) does not support SMS MFA authentication for end-users configured on FortiAuthenticator as a native LDAP server, because a FortiAuthenticator native LDAP server does not allow FTC to query users' phone numbers. Therefore, FTC does support SMS MFA for FortiAuthenticator end-users configured as remote users in a remote LDAP server.
