[Bug 721110] Re: users in nopasswdlogin group are asked for a password and locked

2011-02-18 Thread Carlo Marcelo Arenas Belon
this is somehow similar in use to #674563 but which is instead using
empty passwords which had been deprecated by the nopasswdlogin
functionality upstream as detailed in #393854.

note that the later bug mentions the need to add this also for gnome-
screensaver but that was somehow forgotten probably because of the long
discussion.

[Bug 674563] Re: Passwordless users are prompted for their password when the screen locks

2011-02-17 Thread Carlo Marcelo Arenas Belon
the ubuntu way of managing passwordless users is not through the use of
empty passwords (which are dangerous as they will also allow free access
to the machine services like ssh for that account), but using locked
passwords (which will look like the account is disabled in gnome users
settings) but enabling them to login without a password through gdm by
adding them to the nopasswdlogin group (the don't ask for password on
login checkbox) when adding a user and then managed that as an exception
through pam.

sadly the same problem described here would happen to those since gnome-
screensaver is unaware of that special group and the workaround is to
click on swich to another account and then selecting your own account to
get out of the lock

[Bug 721110] [NEW] users in nopasswdlogin group are asked for a password and locked

2011-02-17 Thread Carlo Marcelo Arenas Belon
Public bug reported:

Binary package hint: gnome-screensaver

release: 10.10 (maverick)
version: 2.30.0-1ubuntu1

replication instructions :

* create a new user account and when requested for a password select the option 
to not ask on login
* login with that new account
* press ctrl+alt+l

problem description :

since there is no password for that account the password prompt makes no
sense and can't be resolved keeping the account locked.

additional information :

gnome allows for the creation of accounts that are not required to enter a 
password to login by creating them with a locked password but as part of a 
special group named nopasswdlogin which then is authenticated to login by gdm 
through its pam
as shown by :

  gdm auth  sufficient  pam_succeed_if.so  user ingroup nopasswdlogin

adding the same line to /etc/pam.d/gnome-screensaver would allow for
this accounts to be able to get back to their sessions if locked by the
screensaver
