VirtualDomain support is not working with sendmail/cyrus/ldap

[BipinDas]

Dear List,
I do have a Sendmail/Cyrus server with LDAP as backend. Sendmail deliver =

mails to the default domain. I had add the virtualdomain support in =

Cyrus. I had add a new user named test at aaa.com. But when try to login =

through webmail,cyrus shows the following error.
*
/var/log/syslog*
---------------------------------------------------------------------------=
----------------------------------------------------------------------------
06:59:12 cyrus cyrus/imapd[12664]: badlogin: [xxx.xx.xxx.xxx] plaintext  =

test at aaa.com.SASL(-13): authentication failure: checkpass failed.
---------------------------------------------------------------------------=
----------------------------------------------------------------------------
My Configuration setups are as follows
*
/etc/imapd.conf*
-------------------------------------------------
virtdomains: yes

defaultdomain: exampleisp.net
------------------------------------

*/etc/mail/sendmail.cf*
--------------------------------------
define(`confLOCAL_MAILER', `cyrusv2')
MAILER(`cyrusv2')
--------------------------------------

Did I miss anything or Need little bit more stuff ?
