BUG: nopassword doesn't work with CRAM-MD5

[Arkadiusz Miśkiewicz]

Hello.

dovecot 2.2.26.0

When testing nopassword extra field 
(http://wiki2.dovecot.org/PasswordDatabase/ExtraFields) with CRAM-MD5 dovecot 
doesn't allow any password (while it should) and returns

" Authentication failed"

while in logs:

Nov 17 08:22:34 auth-worker(1551): Info: 
sql(pepe,127.0.0.1,<Y8amDXpBptV/AAAB>): Requested CRAM-MD5 scheme, but we have 
a NULL password 

NULL is there because our sql query returns empty password just like wiki says 
"nopassword:  you want to allow all passwords, use an empty password and this 
field. "


If password is returned in sql query then it fails, too:

Nov 17 09:00:49 auth-worker(2206): Error: 
sql(pepe,127.0.0.1,<eO5vlnpBtNd/AAAB>): nopassword set but password is non-
empty

So looks to be a bug.
