Looking a bit more at this:

Our sync server does advertise the correct mechanism

synctest -m PLAIN -t "" alpenwurst2
S: * SASL GSSAPI
S: * STARTTLS
S: * OK alpenwurst2.cc.columbia.edu Cyrus sync server v2.3-alpha
C: STARTTLS
S: OK Begin TLS negotiation now
verify error:num=19:self signed certificate in certificate chain
TLS connection established: TLSv1 with cipher AES256-SHA (256/256 bits)
S: * SASL PLAIN GSSAPI
S: * OK alpenwurst2.cc.columbia.edu Cyrus sync server v2.3-alpha
Please enter your password:

My quick guess is your only mechanism is PLAIN and since you didn't 
specify -t ""  to do a TLS connection, PLAIN is not being advertised. That 
leaves you with no mechanisms left and just the error.

Try the '-t ""' and maybe a '-m PLAIN' and let me know how it goes.
