-25590 Authentication error

Hello! I have downloaded from Intraware Informix Client-SDK 2.3 for w95/w98. I connect with no problems from Excel, Access, Vb5 to database Informix-SE 7.2 under SCO OpenServer 5.0.5 from my machine. I have installed the same product on another machine and I am not able to connect. I have the -25590 error. finderr gives me poor help. -25590 Authentication error This error indicates that an invalid user ID or password was used to connect to the database server. Redefine a valid user ID and password. This error can also occur if the SCM option is enabled on the database server side but disabled on the client application side, or vice versa. If you wish to use a CSM, make sure that the CMD option is set in the sqlhosts file for both the database server and client application. Any ideas? What do i missed?
