[Dovecot] v1.2 can't set ACL to empty string

Hi *,

according to RfC4314 the rights argument to the setacl command might be an empty string ("zero right characters"):

The third argument is a string containing an optional plus ("+") or
minus ("-") prefix, followed by zero or more rights characters.

existing clients (horde in particular) actually use this to remove all rights from an user.

Currently dovecot 1.2 does not accept an empty rights string as argument to setacl. Bernhard Herzog will look into this.

cheers sascha
