This was not a problem in my nix setup.
After I looked at the key setup on a Fedora and an Arch system I noticed that these did not have a Default_keyring, and all the passwords were in the Login keyring. The Login keyring only had a key to unlock the Default_keyring. I then:
- Deleted all the mailnag keys in the default keyring.
- Right clicked on the Login keyring and made it the default keyring
- Ran mailnag-config and reentered my passwords.
The new entries ended up in the Login keyring, and when I rebooted and logged in mailnag was
able to find them.
I’m not sure how the keyrings got set up the way they did, but I have been running Gnome from before the time that the pam setup had been worked out and I was regularly prompted by the gnome-keyring for my password every time I logged in.
Thanks for the help and sounding board to work out the issue. At least there is some documentation on the net about a solution. I know I looked a long time and found nothing.
