Can't authenticate to Online: password incorrect?

We are running Online 7.22 on Unixware 2.1, Compaq Proliant 1500. Users are able to telnet into the system and fire up `dbaccess`. However, suddenly, they cannot access Online via their Delphi front-end program, even though they are typing in the same login and passwords as when they telnet in. At the PC end the users see the following error messages: [Intersolv][ODBC Informix driver] [Informix]User's password is not correct for the database server. [Intersolv][OBDC Informix driver] [Informix] No such file or directory. Alias: debit. The following error appears in the online.log file after an unsuccessful attempt is made: 14:13:53 listener-thread: err = -952: User's password is not correct for the database server. Since these messages appear in the backend Online.log file, I assume that the connectivity is not the issue - they are definitely connecting to Online, at least for an authentication attempt. I'm not sure how the authentication process works when logging in via Online, but I imagine that Online passes the login: and password: data on to the OS for checking if the passwords are correct. What goes on between Online and the OS that could be mis-operational??? The only thing that has changed, as far as I can recall, is that we upgraded from Online 7.21 to Online 7.22. But this shouldn't have had any effect on the login process, right???
