Package: gnome-system-tools
Version: 3.0.0-5
Severity: important

Dear Maintainer,

While adding a new user there is no PAM interaction with users-admin,
effectively allowing users-admin to disregard all PAM restrictions until the
user creation actually takes place. The result is, the new user has a locked
account and extra action is required to set a working password.

In this specific case libpam-cracklib is configured like this:

/etc/pam.d/common-password:
password        requisite                       pam_cracklib.so retry=3
minlen=8 difok=3 enforce_for_root

When adding a user via adduser, if the password checks defined above fail, a
new password is requested. But when the user is added with /usr/bin/users-admin
no checks take place. So when the user creation is performed, if the password
is weak, PAM creates a ":!:" password field in /etc/shadow, effectively locking
the new user out with no warning to the administrator.
