Steps to reproduce:
1. In Nautilus, select Connect to Server
2. Enter ftp server address, select FTP (with login) as type
3. Enter credentials,
4. select ”Remember this password”
5. Connect.
6. Disconnect.
7. Do steps 1.-2. again with the same server.

What happens:
The User name and Password fields remain empty. You have to enter your credentials again if you want to connect.

What I expect to happen:
For the Password field (at the very least) be automatically filled when I enter the associated user name. Better yet, remember and suggest (as default) both the User name and Password used previously.

Alternatively, just use ~/.netrc if that’s available and has the credentials (see Bug #963042).
