HELP: wrinting dovecot-sql.conf to authenticate to an existing database

hi all, 

can anyone help me with dovecot-sql.conf please ? I'm not a mysql expert and I'am trying to authenticate dovecot2 to an existing database.


I have a database "egroupware" with table "egw_accounts". The field "account_lid" is the full email address and "account_pwd" is the password in Blowfish format.

Here is my dovecot-sql.conf

driver = mysql
connect = host=localhost dbname=egroupware user=egroupware password=*********
default_pass_scheme = BLF-CRYPT
password_query = SELECT account_pwd AS password FROM egw_accounts WHERE account_lid = '%u'



when I try to login to POP or IMAP I got this error in mail.log/mail.info

Error: sql(hidden at mydomain.com,::1): Invalid password in passdb: crypt() failed: Invalid argument
auth: Debug: client passdb out: FAIL#0111#011user=hidden at mydomain.com
dovecot: pop3-login: Debug: Ignoring unknown passdb extra field:

I think I'm having trouble with the password value that is stored in the account_pwd as: 

{crypt}$2a$12$XTAolzXgwMC211MuZELQUedPv9tjZNs7Osh97PnZ50pAKuk3WPGmS

Reading at http://wiki2.dovecot.org/Authentication/PasswordSchemes

I suppose that the heading "{crypt}$2a$" instead of a simple "$2a$" (witch identifies a Blowfish password) is my problem.

How can I fix this ? 

Here is my dovecot -n output:
