[ale] pam vs. shadow passwords

[chiang at nwisgw3.ic.ornl.gov (Lisa Chiang)]

Can anyone explain the difference between these two methods?

I know that Redhat uses pam to control access to xdm etc... but where is the
Suse equivalent? Does pam create encrypted user passwords like shadow or are
they mutually exclusive?

Thanks.
