Postfix SMTP auth doesn't work with cyrus-sasl 2.1.25

[Quanah Gibson-Mount]

I'm curious if anyone has tested Postfix SMTP auth in conjunction with 
Cyrus-SASL 2.1.25.  My testing shows that when used linked to Cyrus-SASL 
2.1.25, SMTP auth fails with an unknown mechanism error.  Downgrading to 
Cyrus-SASL 2.1.23 with the exact same configuration and build parameters 
works as expected.

My guess is this is an bug with Cyrus-SASL 2.1.25, however it is entirely 
possible there are API changes in 2.1.25 that Postfix needs to be adjusted 
for.  I guess consider this a general heads up, and if anyone has gotten it 
to work, I'd love to know that. ;)

A 2.1.25 linked Postfix always complains about no available mechanism:

openssl s_client -connect zqa-062.eng.vmware.com:25 -starttls smtp -cipher
