 <UL>  
 <PRE>You can do this by these 5 steps:  
 1. enter the system command, as "root", pwunconv  
 2. enter the system command, as "root", grpunconv  
 3. Set the following to be the /etc/pam.d/login file on your system  
 #%PAM-1.0  
 auth       required     /lib/security/pam_securetty.so  
 auth       required     /lib/security/pam_pwdb.so shadow nullok  
 auth       required     /lib/security/pam_nologin.so  
 account    required     /lib/security/pam_pwdb.so  
 password   required     /lib/security/pam_cracklib.so  
 password   required     /lib/security/pam_pwdb.so nullok use_authtok  
 session    required     /lib/security/pam_pwdb.so  
 session    optional     /lib/security/pam_console.so  
 4. Set the following to be the /etc/pam.d/passwd file on your system  
 #%PAM-1.0  
 auth       required     /lib/security/pam_pwdb.so shadow nullok  
 account    required     /lib/security/pam_pwdb.so  
 password   required     /lib/security/pam_cracklib.so retry=3  
 password   required     /lib/security/pam_pwdb.so use_authtok nullok  
 5. Set/reset passwords.  As "root" use 'passwd', and 'passwd www'  
 to change the important passwords.  This creates crypt-processible  
 passwords in /etc/passwd.

 <P>  
 In the future, LON-CAPA Installation will be distributed on a CD complete with a
