If krb5_store_password_if_offline = true the plain text password is saved in the kernel keyring until the user connects to the home network or the system is shut down - which in the days of suspend/resume might mean days or even weeks. It should be possible to configure this storing period.
Idea from comments at https://lwn.net/Articles/457415/.

priority: major => minor
type: defect => enhancement
version: 1.6.1 => master
