KWallet has the ability to open kwallet on login now (https://projects.kde.org/projects/kde/kde-runtime/repository/revisions/f2fe3e75b4ba12d0f99aa09327059a1865891b14), but I can't find any information on how to enable it. What information needs to be changed in /etc/pam.d/ and maybe other places for me to make it work?

I am running Arch x64 KDE SC 4.13 with Workspace 4.11.8

This feature is still experimental at this stage, and requires the installation of a PAM module which has yet to be released.
I can ask the author however if you're still interested - however self-compilation of software will be required.

Hi,

thanks for the offer. I would have said yes, but since an explaining blogpost has appeared on planetkde this is no longer necessary.
