    Question PAM Authentication to AD - Hash kept?


    Question: When you are using PAM to authenticate to Active Directory, is a hash of the password kept on the Linux System?

    It was my impression that it wasn't. In fact, it was my impression, based upon the logs I see that first it tries the PAM authentication and if that fails tries the local authentication.

    So if the connection to the AD was down, AD was down, you could retain an original password and still get into the box.

    (I am a security person, not a Linux expert).

    That was my understanding that your windows user logging into a linux box was different than local account. However I did a quick search and you can have it cache the credentials like windows does. This link gives some extra information. pam_winbind
