Hey John, looks as if your SASL (CyrusSASL) installation was incomplete or defective as it fails identifying mechanisms usable for authentication:

How did you install CyrusSASL, which SASL authentication plugins did you install? A common place to look at would be "/usr/lib/sasl2” - that folder would show the installed plugins. Mind that the exact location depends on your distribution or build configuration in case you installed things manually.
