[Pkg-shadow-devel] Bug#892098: passwd: useradd in Jessie creates user with empty string as shell

[Martin Steigerwald]

Package: passwd
Version: 1:4.4-4.1
Severity: normal

Dear maintainers,

useradd in Jessie creates user with empty string as shell:

% useradd -m emptyshell    
% getent passwd | grep emptyshell
emptyshell:x:4001:4002::/home/emptyshell:

% useradd -D
GROUP=100
HOME=/home
INACTIVE=-1
EXPIRE=
SHELL=/bin/bash
SKEL=/etc/skel
CREATE_MAIL_SPOOL=no

useradd from passwd 1:4.5-1 in Debian Sid works correctly.

Thanks,
Martin
