Where should I look for those messages?  I don't see anything from the 
shell when I run the command other than:

# sasl2-sample-server -m GSSAPI -s smtp
trying 2, 1, 6
trying 10, 1, 6
socket: Address family not supported by protocol

and in the syslog:

Apr 30 12:30:24 SBSMTPNV03 sasl2-sample-server: auxpropfunc error
