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

[Sascha Wilde]

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
