Yubico Forum

By adding into common-auth:

auth sufficient pam_yubikey.so

And reading the documentation I would have thought I could login also through su and kupdateapplet but this fails.

I can login to console with Yubikey, I can sudo bash -l (rendering su - unnecessary, but still I want it to work), but a real bug bear is kupdateapplet not accepting yubikey as sufficient as I am having to always manually update.

I don't know enough about PAM to configure it to work so I can use my Yubikey to login via su without a password and same with kupdateapplet. This is kind of stupid because I have in the past written my own PAM module.

Anyhow, if you can help me please do I love my little yubikey and I'm going to try and get it into all sorts of interesting places...

OS is OpenSUSE 11.2

And now you can use the module for packagekit, etc. There probably is a point to that check (stop from trying to brute force anthers pass??? but it makes the module crippled)
