I cannot help you if this really is a Mac issue, but the error message 
sounds to me like your server is not configured to accept connections 
from your client. When you say it works with a different OS, do you mean 
on the same machine, or do you mean on a machine with a different IP 
address?  If the latter, then be sure the server has the same 
permissions for the two machines, then check that the odbc.ini files 
have the same UserName and Password settings, just in case that is 
really what is being used, rather than the strings in the command line. 
You should also be sure the host server setting is the same on both 
machines, just in case you happen to be talking to different servers.

(I do realize that you probably know this, but it is surprisingly 
difficult to get these right, and the error message you get when they 
are wrong is the one you are getting.)

Another thing you can do is to run the server in debug mode, which 
sometimes gives better details about attempted connection failures.
