Linux authentication

Does linux support a replacement of its username/password collection UI in x-windows. To specify, I have a windows authentication method that uses开发者_运维百科 gina/credential providers to display an alternative to the usual username and password. I wish to port this to linux.

I realise that text-mode runlevels will not support this, and only x-windows would.

Yes. All the components are open source, and if you're lucky don't need much modification. PAM = Pluggable Authentication Modules, and then you need a GUI like GDM/KDM/XDM to collect whatever you need to pass to pam for authentication.

This is basically what everyone has already told you in comments...
