saslpasswd2 without password prompt

[Yadavenedra Awasthi <yadu@xxxxxxxxxxxxxxxxxxxxx>]

Hi,

I am trying to give below command so that it should not ask for password 
authentication but it is still asking for password authentication :

 saslpasswd2 -p -c -a smtpauth test@xxxxxxxx test

Please let me know is it possible to add username and password in a 
single command line without promptimg for password in stdin.

Regards.
Yadavendra.
