I tried to import an ssl cert via the gui (i.e. I double-clicked a .cer file and clicked the "Import" button). I was prompted to unlock the "Gnome2 Key Storage" certificate/key store via one of those Gnome 3 full-screen auth prompts.
I couldn't unlock it. None of the passwords I've used on this machine have worked, so either I've been crafty and set it to some other password that I've now forgotten, or something is broken.
I get the same result from seahorse ("Passwords and Keys"): Certificates -> Gnome2 Key Storage will not unlock with any password I've got. I've tried running seahorse as root using gksu, which didn't work either.
How can I reset the password for this cert store? I'm happy for the contents to be deleted, so if there's a file I need to remove that's fine.
I'm aware of the answer in this question, but that resets the login keyring, not the Gnome2 Key Storage keyring. Maybe I could do the same thing for the Gnome2 Key Storage keyring, but I don't know where it lives on disk.
I'm running Gnome 3.12 on Ubuntu 14.10 (upgraded from 13.10 -> 14.04 -> 14.10).

So I'm not entirely sure this is exactly what you want to do but I'm having the same problem so I resorted to CLI:
Make sure you have libnss3-tools installed
This worked like a charm for me. It doesn't solve the GUI issue but at least I don't have to verify each one of my company's internal CA-based sites.
For the record, I got the info from here.
