Thanks for following up. This is likely a duplicate of bug 238755. The later has been fixed in shadow package a while ago but it appears that debian/patches/494_passwd_lock-no_account_lock has been applied upstream in 4.1.3 and hence dropped from Debian/Ubuntu.
Another report with the same use case but with vsftp is bug 484004
Confirming this report and adding a task for shadow. I'll let a developer handle it from here and mark it as duplicate if it's really the case.
