However, the IBM Redbook recommends 600 permission for
certificates.

Local fix

  • Give 644 Permissions to .tls directory and certificates.

Problem summary

  • When 600 permissions are set to certificates, FTP over TLS will
error out for non-root users

Problem conclusion

  • Code changes made to assign proper privileges for non-root
users to perform FTP over TLS

Temporary fix
