1) ibvpn's user names are e-mails (ex: firstname.lastname@example.org
). The GUI does not allow you to enter the "@" symbol in the user name field, although the keyboard allows it.
2) When trying to connect, I get a "connection failed" error on PPTP connections (encrypted or unencrypted). The authentication does not seem to work properly. Nothing seems to be logged anywhere as to the reason of the failure.
