Netextender does not recognize scandinavian umlauts
we are using a Sonicwall TZ300 to connect to our work network with VPN. The VPN client is Netextender version 9.0.277. Some of our users can't connect with the client, they get an error invalid username/password. We found out the reason is they have nordic umlauts in their password (such as ä,ö,å). After changing the password to one without umlauts, the connection works. Is there a way to make sonicwall recognize special letters such as nordic umlauts? Maybe a firmware upgrade?
