Postfix-Cyrus-imap-Web-cyradm-Cyrus-sasl-mysql

[rm-eksi-rf rm-eksi-rf <rmeksirf gmail com>]

hi, my problem is running postfix with cyrus-sasl, cyrus-imapd, 
web-cyradm, mysql.
I dont run together, always get error messages. I had spent time 2
month. But not run still.

May  2 10:29:47 space saslauthd[4914]: returning 7 after db_checkpasswd.
May  2 10:29:47 space saslauthd[4914]: do_auth         : auth failure:
[user=cyrus] [service=imap] [realm=] [mech=pam] [reason=PAM auth
error]

What must I do? Please help.
