I have a webapp on our intranet that authenticates against zimbra's ldap server. I am writing a simple zimlet that opens the above webapp in a pop-up iframe. I would like to pass username and password to the iframe so that it logs the user in automatically. I have obtained the username as simply as appCtxt.getActiveAccount().name but I can not figure out how to get the password the user typed in to log in to zimbra. Is this at all possible?
