Cyrus-Imapd SERIOUS problem Please HELP

[Sleepy Chanterelle]

Well i have set up a postfix mailserver with cyrus sasl for smtp auth , cyrus imapd as the IMAP with Mysql as a back-end. Authentication is being done with pam-mysql
I have a strange problem. When you enter a valid username you can login with ANY password, the IMAP responds .. OK User Loged in.

i tried Almost ALL the how-to that exist but i couldnt find anything. so my last chance is to post here my config files and tell me IF there is a chance of fix that thing. Sorry for my big log but i am desperate  .

in order NOT to make a HUGE link i will post the config files in links so you just click the link and you see the config 

postfix main.cf -> www.nightwish.gr/postfix/main.cf
cyrus -> www.nightwish.gr/postfix/cyrus.conf
cyrus-imapd -> www.nightwish.gr/postfix/imapd.conf

mysql virtual files of postfix
www.nightwish.gr/postfix/mysql_virtual_alias_maps.cf
www.nightwish.gr/postfix/mysql_virtual_domains_maps.cf
www.nightwish.gr/postfix/mysql_virtual_mailbox_maps.cf

the files of pam.d
www.nightwish.gr/postfix/imap
www.nightwish.gr/postfix/smtp

and finaly the cyrus-sasl file
www.nightwish.gr/postfix/smtpd.conf

and finaly see the output from the /var/log/messages
