You should first turn on auth_debug 
(http://wiki.dovecot.org/Debugging/Authentication) and mail_debug for 
the managesieve service to get more log messages. The 'Disconnected' 
reason occurs when the client abruptly terminates the connection, 
without issueing a LOGOUT command. This might be caused by a failed 
login, but something else might be the problem as well.

I notice that you are using pam and that your args is set to '*'. This 
means that dovecot authenticates with pam using the servicename of the 
service involvend; e.g. imap or pop3. So, did you add a managesieve 
service to your pam configuration? My experience with pam is close to 
zero unfortunately, but you can read 
http://wiki.dovecot.org/PasswordDatabase/PAM for a few pointers.

If all this isn't the problem, try disabling TLS and sniff (e.g. using 
ngrep) the ManageSieve TCP session to see what is going on between 
client and server.
