Hi Daniel,
Applying any change to any field in the NetworkManager strongswan VPN plugin config will write a text config file with the 'certificate=' line.
As I said, I can't reproduce this. I can change whatever in the GUI, no "certificate=" line is added to the config file.
Notice the missing 'certificate=' line. However, any change made in the GUI would restore the certificate= line as show below:
I don't see how. The GUI checks gtk_file_chooser_get_filename() and only if that returns a value != NULL will "certificate" be written to the config. That's why I was asking what the GUI actually displays in that file chooser in your case.
According to the reference [1], NULL is returned "if no file is selected, or the selected file can't be represented with a local filename", I don't think an empty string should be returned.
Alternatively, strongswan should assume 'certificate=' indicates the system certificates should be used.
Yes, we could add a check for an empty string, but the setting shouldn't be there with an empty string in the first place.
