Comment 7 for bug 91964

Same problem here. I need to just save group password, and not user password. I dont want to hunt for my group password whenever I need to log in.

Current workaround that I am using is:
Login successfully once by entering manually the userpassword and grouppassword, and ask for both passwords to be saved in ring(unchecking the session save thing).

The next time when you try to connect to vpnc, vpnc tries to connect using this pair, which obviously fails. Try re-connecting immediately after failure. This time, the dialog pops up with the last saved user/group password. Change just the user password and login successfully.

You will be an eye-sore to the admin when he goes though vpn log, but I think he will be happier to know that you haven't left the group password in the clear somewhere to use everytime you log in.
