Comment 14 for bug 1725062

Tomas, I forgot to mention - workaround works for me only on saved connection. You need to create it first,save it and then choose 'save password for all users' option. If you change anything else after choosing 'save password..' option, the problem may be persist. Also i assume your problem is a little bit broader. If I right, and you need PPTP connection for RDP sessions - it won't work out of the box in Ubuntu. You need to upgrade remmina from ppa, and check 'send echo packets PPP' and check 'use these connection for these network resourses only'. Aslo i recommend to try to connect via 'nmtui' the way i mentioned above, if my workaround not working.
