problems with authentication

[Ali Asad Lotia]

hello all.

i am having trouble authenticating the the imapd. the details of my  
installed system are:

sasldb is at: /etc/sasldb2 the cyrus user can read the /etc/sasldb2  
file.

my /etc/imapd.conf file:
configdirectory: /home/cyrus/imap/config
partition-default: /home/cyrus/imap/mail
lmtpsocket: /home/cyrus/imap/config/socket/lmtp
idlesocket: /home/cyrus/imap/config/socket/idle
notifysocket: /home/cyrus/imap/config/socket/notify
admins: gulkhan
sasl_pwcheck_method: auxprop
sasl_auxprop_plugin: sasldb
sasl_sasldb_path: /etc/sasldb2
unixhierarchysep: yes
altnamespace: yes
quotawarn: 90
singleinstancestore: yes
duplicatesuppression: yes
sievedir: /home/cyrus/sieve
hashimapspool: true

sasldblistusers2 shows:
test at lotia.org: userPassword
gulkhan at lotia.org: userPassword

when i try to connect using imtest:
  ./imtest -a test -r lotia.org localhost

(output)

trying cyradm

./cyradm --user gulkhan --auth DIGEST-MD5 192.168.1.11
Password:
