Title:
Impossible to patch gnome shell to set a custom ShellUserVerifier
Status in gnome-shell package in Ubuntu:
Fix Released
Status in gnome-shell source package in Noble:
In Progress
Bug description:
[ Impact ]
GNOME Shell in ubuntu is also used to show custom user verifiers in
order to be able to login with specific authenticators, but since
version 46 extensions providing this are not working anymore.
This is due to the fact that it's not possible anymore to override the
shell verifier from a GNOME extension.
In particular, AWS's Amazon DCV requires an extension in order to login, and
this does not work anymore in GNOME 46:
- https://github.com/aws/dcv-gnome-shell-extension
Without this extension, the shell native authenticator can't be
bypassed in AWS installations when the web authentication has
validated the user credentials.
[ Test case ]
To verify that the the function can be overridden, a new symbol has to
be exported.
Use the gnome shell looking glass (Alt+F2 -> 'lg' -> Enter) and paste
this code:
import('../gdm/authPrompt.js').then(m => Main.notify("Found",
`${m.AuthPrompt.prototype._createUserVerifier ?? false}`))
A notification should be shown with the function code, while it should
not contain the word "false" only.
This can also be verified installing the extension
https://github.com/aws/dcv-gnome-shell-extension and it should load
without errors in the journal
[ Regression potential ]
It's just a simple abstraction of few lines of code, so potential is
very low, but potentially the GDM user verifier (and so the user list)
may not be loaded.
