Caja doesn't remember passwords for remote shares

Linux Mint 12, fully patched as of this writing; Caja 2011.11.10.

I regularly need to access files on another computer in our house. When I go to the directory on the other computer, Caja prompts me for a password and offers the following options:

- Forget password immediately.
- Remember password until you logout.
- Remember password forever.

I have selected "Remember password forever", but the resulting behavior is "Remember password until you logout". I have to enter the same information the next time I log in and need to access those files. I installed Linux Mint 12 the day after release, and have duplicated this behavior several times.

This is not a showstopper for me; it's a minor inconvenience in the whole scheme of things. However, it is a regression.

(Possibly useful information: The other computer, where the files reside, runs on Mageia. Nautilus, on the Gnome 3 "side" of Linux Mint 12, does remember the passwords in between sessions.)

Thanks for your attention, and for all the work you've put in getting Linux Mint 12 to work as well as it does.
