local-smb.conf is an empty file.   I don't have another encrypt passwords = 
yes anywhere in the config file.

What is weird is that I can eventually authenticate after I change the 
username I try to authenticate with and then change back again.

So, this looks like a bug?  I wonder whether it only effects Solaris 
systems.  I would have thought others would have fallen across it.

I can't code, but I can provide logs and testing.  Please let me know if I 
can help at all.
