[Pkg-auth-maintainers] Bug#706067: libpam-dynalogin: crashes when connection to server cannot be established

[Petr Čech]

Package: libpam-dynalogin
Version: 1.0.0-1
Severity: normal
Tags: upstream patch

Hi,
when the dynalogind server does not run, the PAM module segfaults. The following
patch solves the problem (for me, at least).

Regards,
Petr
