Description Johnray Fuller 2000-10-17 10:46:43 EDT

Mark Wolfgang actuallty found this one,.

The bug occurs if the user uses this command to enter a new user's

useradd newuser -p password

The password under this command is stored in plain text in the /etc/shadow
file. this of course prevents the user from logging in.

Take care,
Comment 1 Nalin Dahyabhai 2000-10-17 12:16:41 EDT
As documented in the man page, the -p option expects an already-crypted
password.  Use
python -c 'import crypt;print crypt.crypt("password","salt")'
to generate a suitable value.  Use a salt of "$1$jrHrLTgH" or something similar
to get an md5crypt hash instead of a standard crypt hash.
