zimlet to get userpass

[jerryboi]

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?

Search the wiki for the word 'preauth'.

TY.

I have already seen that preauth is possible, but I was hoping that I could just find the plaintext passwd in a var and would not need to create a new login page. It is not a big deal though.

Thanks again.

Passwords are not stored in plain text they're encrypted, for obvious reasons.
