listener-thread: err = -951

Good Day , IDS 11.7FC8 HP-UX 11.31 We have set up a completely new server(hardware&OS) and installed IDS 11.7FC8. When the users try to log on we get the following error in the online.log: " listener-thread: err = -951: oserr = 0: errstr = user@server : Incorrect password or user "........" is not known on the database server. Can somebody please tel me how to fix this? My e-mail address is zanelema@raf.co.za Thank you in advance

Look for yu applications one by one. Ther are attempts with wrong password or unknown user. On Unix/Linus machines Informix IDS by default use the OS user/password
