Postfix courier mysql squirrelmail

[deco5003]

I follow the guide Virtual Users and Domains with Postfix, Courier, MySQL And Squirrel Mail (Debian Lenny) Now I got postfix running ,after many working hours . It seems to me that is not working with amavis I need to remove and then install amavis new, also I modify some lines on master.cf Now I have response from Telnet 110 and telnet 25 passing the squirrelmail test. But now the problem is with authdaemon is not authenticating users Through Mysql. Viewing mail.log I got that:
Aug 26 18:22:12 dec1 postfix/master[11937]: warning: /etc/postfix/master.cf: logical line must not start with whitespace: " $
Aug 26 18:23:39 dec1 postfix/master[11937]: reload configuration /etc/postfix
Aug 26 18:24:45 dec1 imapd: Connection, ip=[::ffff:127.0.0.1]
Aug 26 18:24:45 dec1 imapd: authdaemon: s_connect() failed: No such file or directory
Aug 26 18:24:45 dec1 imapd: LOGIN FAILED, user=admin@deccom.com, ip=[::ffff:127.0.0.1]
Aug 26 18:24:45 dec1 imapd: authentication error: No such file or directory
Is there something wrong with authdaemon? Iits not authenticating with MySQL. Something is missing on the configuration or with the authdaemon installation. Thanks for your help
