[Dovecot] Authentication without password

Hi all,

for one of my developpements, I need to be able to connect an IMAP
server with a login but without password.

(I use dovecot 1.0.beta3)

For the userdb, I use "userdb static" :

userdb static { args = uid=114 gid=114 home=/mydev/mail/%u }

But I don't know how to allow IMAP connection by my application
without password.

I won't connect to a database, having a user/password file or
something like this ...

I think to use "passdb checkpassword" to call a fake authentication
script ....

Anyone have a better idea ?

Thanks,

Cyril Feraudet
