ftpuser:x:504:500::/u02/backup/appltrng/apps/apps_st/appl/xxace/12.0.0/reports/US:/bin/bash

to
ftpuser:x:504:500::/u02/backup/appltrng/apps/apps_st/appl/xxace/12.0.0/reports/US:/sbin/nologin

Step 7: allow chroot local user in ftp

[root@ebsdev vsftpd]# pwd
/etc/vsftpd
[root@ebsdev vsftpd]# vi vsftpd.conf

Add below Bolded line

# You may specify an explicit list of local users to chroot() to their home
# directory. If chroot_local_user is YES, then this list becomes a list of
# users to NOT chroot().
#chroot_list_enable=YES
chroot_local_user=YES

Step 8: restart vsftpd service

[root@ebsdev vsftpd]#service vsftpd restart

step 9: Try to login with credentials in ftp and also putty terminal

You can’t login in putty but you can able to login FTP with home path which directory you configured, you can’t go other directory. you have only that directory access.
