Red Hat Bugzilla – Bug 825525
Passwordless user (such as guest) cannot select session
Last modified: 2012-05-27 23:55:17 EDT
Description of problem:
GDM allows a user to select the session they wish to log into (those under /usr/share/xsessions/ such as GNOME, Xfce, KDE, etc). This option however, only occurs after a user has been selected from the list. Selecting a user would ordinarily prompt for the password, however if a user has no password they are automatically logged in with no chance to choose their session/desktop.
In addition, other than simply clicking on the user one can select "Not listed?" and type in the passwordless user's username. This presents a list of sessions, however upon pressing "Sign In" the selected session is reverted to last session and is therefore unsuccessful.
This is particularly an issue for Live CDs where the liveuser has no password, but remixes/spins might have multiple desktops. This may also affect a guest user (xguest?) however I couldn't get this user to show up in gdm so was unable to test.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Create a user: useradd testuser
2. Remove user's password: passwd -d testuser
2. Install or create another session.desktop file (e.g. xfce-utils)
3. Attempt to log testuser in to a specific session
User cannot select a session, logs into default (gnome.session).
User should be able to log into any available desktops.
