GDM Enterprise Login

Rationale

We want to be able to get kerberos tickets at GDM login time so we need network access, in the case of public WiFis with captive portals GDM won't show the captive portal prompt for a public wifi.

Current problems

• No ability to select wifi APs GDM
• GDM can't show an application window
• The web client should run sandboxed

• WebkitGtk+/libsoup doesn't support GSSAPI
