Ploblem with creating user withount domain part (cyrus-sasl2-2.1.19)

[Sergey]

Hello.

Can I create sasl user without domain ? I attemt to run 
cyradm --user cyrus localhost
but password isn't accepted:
# cyradm --user cyrus localhost
Password:
Segmentation fault
#
(another question: Is "Segmentation fault" normal for bad password ? 
cyrus-imapd-2.2.8 )

I was attempt to create user by 

saslpasswd2 -c -u "" cyrus
saslpasswd2 -c -u '' cyrus
saslpasswd2 -c cyrus

In all cases sasl create login cyrus@[hostname]. I can set cyrus@[hostname]
as cyrus administrator, but I think what it not good.
