The syslog output will tell you when a user authenticates.

If you want to debug something at the protocol level for a particular 
user, you can have Cyrus create telemetry logs of each session for that 
user.  Simply create a directory with the user's authenication id under 
<configdir>/log (e.g. /var/imap/log/beck).  Make sure that the cyrus 
user has write access to the directory.  Then for each of beck's 
sessions, you'll see a separate file in that directory (named by pid of 
the process).  These logs can grow quickly (especially for IMAP), so 
make sure you delete the per-user directory when you're done debugging.
