The only log entry I get on the backend.. even with CYRUS_VERBOSE turned 
up... is this:

Oct 31 11:30:53 is8000new imapd[19749] badlogin: [10.10.100.42] PLAIN 
[SASL (-4): no mechanism available: security flags do not match required]

The tcpdump log for this action follows... ignore the differences in 
time stamps..  This is all I've been able to go by for logs... if there 
is some way of getting more detailed logs from cyrus.. let me know and 
I'll try that.  Oh and no I'm not concerned with passwords.. these are 
all test systems on a private network.
