RE: CAC screen locking/unlocking

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I'm using RHEL4. I think CoolKey kept freezing on me and I ended up with
muscle + commonAccessCard for PAM and CoolKey for Firefox; it's been a while
since I messed with all that because I read some message in a mailing list
archive that said you really shouldn't have anything that takes a PIN in the
same PAM stack with anything that takes a password: when the card is
inserted and removed you should switch between different PAM stacks. This
implies code changes in gdm and the screensaver, some of which I'm sure have
happened in FC6, but I haven't tried them out yet.
