any direction to debug the problem of sasl authentication failure ?

This server is ran for a few years and guy who managed this server was quit and I could not got much information from other colleagues.
I installed centos 5.8 and virtualmin on a virtual machine, sasl ran properly out of the box without special configuration.
When I compared the configurations files from them. Here are what my findings.
the postfix version is different. The VM is 2.3.3, the production server is 2.6.7
the postconf -n more or less are the same accept two lines production server

I just used a utility called saslfinger to list sasl configuration http://postfix.state-of-mind.de/patrick.koetter/saslfinger/
There is a different of master.cf between production and virtual machine box
