Hmm, can't make anything of that, just that it failes to start (i forgot to ask to run it with follow childprocs, but let's forget that)
You said you reinstalled saslauthd, didn't that overwrite some of your configuration settings?
Also, can you see anything related to the saslauthd process in your log files when you try to start it? If there's not enough info, you can set the debug level up, so you get more information in your log files. I'm not really a suse user, so i'm not sure where those sasl config files are but i guess somewhere in /etc/courier/
