I may or may not have blogged about this in the past, but given the nature of my work I use network-manager, vpnc, and network-manager-vpnc a lot. I noticed recently that there was no longer an option to save the group password only in network-manager-vpnc's authentication dialog, something I had already worked on to some extent.
So I looked at it again.
This time, it's been a little more complicated. Given that the current version of network-manager-vpnc comes out of SVN, there has been major changes from 0.6.x which have forced me to revise quite a few parts of the initial patches I had found on FC8. After about 3 and a half hours of work, I can finally say that it works -- and I'm happy about it too, because I see it as a pretty nice accomplishment given that I'm a novice at tackling bugs, far from used to the way code works in Gnome, and much less in a system as complex as NetworkManager.
For those who are actually interested in the results, my patch is up on the gnome bug #363918, and also on the relevant Launchpad bug #262191.
A working (based on the tests I did, anyway) package is up on my PPA, too.
