UYsing nmcli, I have set a network-manager setting that is not supported in the plasma editor (for example 802-1x.subject-match). I understand that not all options can be eaily exposed in the gui, so setting it from the command line is fine with me. However, when I now make an unrelated change using th plasma-nm-editor (for example, changing the AP priority), the changes I made from the cli are silently reset. In case of the 802-1x.subject-match property, this is quite disturbing, as it opens up my laptops to attacks using rogue access points and mitm-attacks. So, please keep any changes written from the graphical client as compact as possible (i.e., only writing the keys that are actually exposed in the gui, or even only hte keys that have been changed), instead of resetting all variables. Reproducible: Always Steps to Reproduce: 0. (create an wifi network "eduroam" with 802.11x authn) 1. nmcli c modify eduroam 802-1x.subject-match radius.example.edu 2. open nm-connection editor in kde 3. change an unrelated setting (e.g., priority), and save 4. "nmcli c show eduroam" shows the "802-1x.subject-match" property has been reset Actual Results: see above Expected Results: 802-1x.subject-match poperty should have been kept I'd consider this a security bug (see above), but I think the group of people affected is not very large.
That property should be already supported in Plasma 5.6.x so your problem shouldn't happen. See https://quickgit.kde.org/?p=plasma-nm.git&a=commit&h=92faca4156698df2aee896dbd3a1a6734be58056. Do you really have version 5.6.4?
Closing, subject match property was implemented a year ago. *** This bug has been marked as a duplicate of bug 364973 ***
