Description of problem:

I can't connect to the Internet via DSL connection. I already experienced this on Debian 8.3 though I can't say if the problems are identical. First, I installed Fedora 24 alpha 7 with network manager beta 2. Today I updated network manager to rc1 by tethering with an android phone and I'm still getting the same result. With journalctl -u NetworkManager.service I see these red errors:

Unable to obtain CHAP password for Lnn-201-21 on ASR-FireFly-ID18 from plugin
CHAP authentication failed

<error> [1459779399.746784] [platform/nm-linux-platform.c:3906]   do_change_link():          platform-linux: do-change-link[5]: failure changing link: f

Unable to obtain CHAP password for Lnn-201-21 on ASR-Tylor from plugin

I attached the full log

I can reproduce this with NM 1.2-rc1 by adding a new DSL connection from nm-connection-editor and trying to activate it. The cause seems to be:

nm-pppd-plugin-Message: nm-ppp-plugin: (get_credentials): passwd-hook, requesting credentials...
nm-pppd-plugin-WARNING **: nm-ppp-plugin: (get_credentials): could not get secrets: GDBus.Error:org.freedesktop.NetworkManager.Settings.Failed: The connection was modified since activation

The patch fixes the problem for me.
