Configuration of CRAM-MD5 SASL method?

Hi all, 
does somebody know how to configure CRAM-MD5 SASL authentication method? I tried the following: 

# cat /etc/sasl2/qpidd.conf 
pwcheck_method: auxprop 
auxprop_plugin: sasldb 
sasldb_path: /var/lib/qpidd/qpidd.sasldb 

#following line stops spurious 'sql_select option missing' errors when 
#cyrus-sql-sasl plugin is installed 
sql_select: dummy select 
mech_list: cram-md5 
# qpid-perftest --count 100 --username guest --password guest --mechanism CRAM-MD5 
2011-08-04 10:34:49 warning Broker closed connection: 320, connection-forced: Authentication failed 

connection-forced: Authentication failed 
# 

qpid debug has: 

2011-08-04 10:33:05 info SASL: Mechanism list: CRAM-MD5 
2011-08-04 10:33:05 debug Management object (V1) added: org.apache.qpid.broker:connection:127.0.0.1:5672-127.0.0.1:54123 
2011-08-04 10:33:05 debug SASL: Starting authentication with mechanism: CRAM-MD5 
2011-08-04 10:33:05 warning Failed to retrieve sasl username 
2011-08-04 10:33:05 info SASL: Authentication failed (no username available):SASL(-6): can't request info until later in exchange: Information that was requested is not yet available. 
2011-08-04 10:33:05 debug Exception constructed: Authentication failed 
2011-08-04 10:33:05 warning Failed to retrieve sasl username 

The same (error 320 and SASL(-6)) I received when using Java HelloWorld program specifying sasl_mechs='CRAM-MD5' . 

Any suggestions what do I wrong? As when I replace "CRAM-MD5" by "DIGEST-MD5" in sasl config file and perftest command line, the authentication passes.. (well, it does not in Java HelloWorld program, but that is another story). 

Thanks in advance for your help. 

Kind regards, 
Pavel

Hi Gordon,

You aren't doing anything wrong, this appears to be a bug in the broker. 
I have raised a JIRA (QPID-3393) and have a fix that I'll commit shortly.
