Multiple-Mechanism Sample Code?

[Henry B. Hotz]

The published sample code seems to only try the first mechanism and  
then quit.  I'm told the "correct" way to do SASL is to try all the  
mechanisms (or at least all the ones supported) and don't quit until  
you've tried them all.  Is there any example code that illustrates this?
