Re: Can't authorize as different user in cyradm and sieveshell

Since nobody answered, I guess, nobody has any idea.
I wonder if anybody uses this feature and it works for you?
I mean I'd like to know if that's just me and something is wrong with my setup or may be that feature isn't functional at all?
Thanks in advance,

Michael
