Password validation fails; session continues

If password validation fails and the session continues, you receive the following reply:
530 PASS command failed
Additional replies might be generated if ACCESSERRORMSGS TRUE is coded in FTP.DATA.
If you receive this reply, do one or more of the following:
  • Ensure all libraries, possibly indicated by ICH420I message, used by FTP are controlled and APF authorized.
  • Ensure FTP is authorized if you are using BPX.DAEMON.
  • Ensure that the FTP daemon has been started from a user ID running with superuser authority if the daemon has been started from the z/OS® UNIX shell.
  • Ensure that an OMVS segment is defined for the login user ID, or that automatic assignment of unique UNIX identities support is enabled.
  • Obtain additional information about the error by enabling tracing with the ACC option.
  • Ensure that the password or password phrase used to log in to FTP was entered correctly and is not expired.
  • If you have activated mixed-case passwords in RACF® or in another SAF-compliant security product, verify that you entered the password in the correct case. Password phrases used to log in to a z/OS FTP server are always case-sensitive even when mixed-case passwords are not enabled in your security product.
  • If your password is comprised of more than one token, verify that your FTP client supports multiple token passwords. The z/OS FTP client supports multiple token passwords if you enclose the password with quotation marks when you code it in the NETRC file or data set, or enter it in response to a prompt.
