encrypted pw vs. plaintext pw.

[Jack]

Hi,

I found that if I store username with PAM encrypted password in a file 
(just like /etc/passwd), email user need to login with plaintext password.
On the other hand, if Cyrus allow encrypted password login eg. encrypted 
by MD5 or NTLM, password stored in the cyrus server need to be in plaintext.

What are the proc and cons of using this both methods? It seems that 
PKCS12 need to be used if I need to take the advantage of both methods.

Sam.
