Bug Description

When authenticating to the system with thinkfinger, the user encrypted home directories are not automatically mounted. Even though this makes total sense, since you will need to supply the password to unlock the encryption key. Having said this, the user should be prompted for the password in case if he/she is authenticated using thinkfinger or similar method. What happens now is when login to gdm using finger swipe, gdm starts loading and nothing happens. No message/warning is displayed. The user just sits there starring at a black screen :-)

My system is Jaunty Beta on Thinkpad T61p:

Okay, I had previously marked this bug a duplicate of another request for fingerprint reader support.

Rather, this is more of 'bug' than a feature request.

Users with encrypted-home should not be broken by their fingerprint reader.

I've marked this as affecting PAM, as I think the fix might be somewhere in the PAM stack, though I'm not sure where.

I'm seeing this too. At first I thought it was an Xorg problem as I turned on compiz at the same time as setting up thinkfinger.

Clearly it is just a matter of needing to actually enter the password to decrypt the home directory.

Hello-

Can we please see your /etc/pam.d/common-* configuration, when you're experiencing this problem?
