I have a VBasic input program on PC which data will eventually be inserted into a physical on AS400. I would like to make the users to login this PC program. 1) Is it possible to verify their IDs and passwords against those on AS400 ? If possible, how am I going to do that ? I know it is impossible to retrieve the ID and password from AS400 but is it possible to send the ID and password to AS400 for checking ?
