Sieve impersonate

[Gabriele Bulfon]

Hi, is there any valid way to impersonate using authorization on timsieved?
I tried with:
AUTHENTICATE "PLAIN" "xxxxxxxxxxxxx"
creating the auth string with a perl script as:
encode_base64($authid."\x00".$username."\x00".$password."")
being :
authid="impersonateduser at sonicle.com"
username="admin"
password="adminpass"
Doesn't work :(
Any help?
