Fortigate sslvpn_login_permission_denied

Users are warned after one day about the password expiring.

I have a user which is matched on a LDAP server. The user also has a FortiToken assigned, but I don't think that's relevant. The user is a member of a firewall local group. It seems that the policy does not process groups, only users. Is this correct? Then what do we need groups for?

But messages are still shown from time to time, since scanning is going on over the internet all the time. Therefore, this post is still very relevant. We discussed a lot of possible solutions and came to the conclusion, that there is no simple way to block these attacks. Did you make similar observations? Did you come to another conclusion? Your comments regarding this events are very appreciated. Two factor authentication prevents an attacker from being able to log in to an account only with username and password. With the third factor, the attacker needs access to additional information like the smartphone in case of push token or a 6 digit number in case of mobile or hardware tokens. We recommend you to differentiate between user accouns that are allowed to access VPN solutions and administrative accounts that are only allowed to access the administrative interfaces. Using another port is an easy but effective measurement if an attacker is only probing the default port of an application.

The CLI real-time debugger allows monitoring of the SSLVPN negotiation: diagnose debug enable diagnose debug application sslvpn -1 now try to establish the SSLVPN connection once the negotiation is done or stopped you can disable the debugger diagnose debug application sslvpn 0 diagnose debug disable. If the SSLVPN connection is established, but the connection stops after some time, you should double-check the following two timeout values on the FortiGate configuration: config vpn ssl settings set idle-timeout set auth-timout The idle-timeout is closing the SSLVPN if the connection is idle for more than 5 minutes seconds. By default this is set to 8 hours seconds. That means, that only users can authenticate over this service that really need to authenticate on the FGT. I found myself really dumb after that!!!
