Captive Portal FAC/FGT

[upllop]

I have a guest WIFI that uses the FAC Captive portal and its all set up as per the guides, Guest gets the captive portal popup, I can see he registers, gets put into the "GUEST" group on the FAC, and the Fortigate uses that group "remote server group" to authenticate, I authorise the user, but he cannot connect, The FAC logs show the error "Authentication failed: NAS cannot find user realm" the Realm is set to local! where the guest group is, so I'm a little confused on the error, any thoughts please?

The error message "authentication failed: nas cannot find user realm" typically indicates a mismatch or misconfiguration between the realm settings on the FortiAuthenticator (FAC) and the FortiGate. In this case, since the realm is set to local where the guest group is located, it's important to ensure that the realm settings on both the FAC and the FortiGate are aligned.
