Description soucym 1998-11-16 13:19:22 UTC

When you add a user with 5.1 it appears to be breaking a
standard (discussed this with a long-time linux user) but
the big problem I found was when adding an account for
myself other than root my password showed up in
/etc/password file IN PLAIN VIEW! It was NOT encrypted until
I ran passwd on it. Then it was encrypted. This is a serious
bug that needs to be rectified due to ANYONE monitoring that
file (/etc/password) they would be able to get users
passwords. I mailed redhat and got a response to
come and post the bug here. So here it is.  Email me if
there is a patch out to fix this already, but I haven't
located one.

The -p option to adduser is to set the *encrypted* password;
it assumes whatever you give it is already encrypted. Notice
if you try to use whatever you specified to -p to login that
it won't work...
