Thanks.

i change vxftpd.conf and vsftpd21.conf's entry "pam_service_name=ftp" to "pam_service_name=vsftpd. ftp accepts password and proceeds to login.

550 Permission denied.

On urh04, user account mytest's home directory is /home/mytest.

The 550 looks like it is likely to do with file or folder permissions, alternatively selinux is blocking access.

Which directory mytest ftp/log into?
Thanks.

It is the chroot directory, where you want to the user should be jailed and should not access to it's parent directory.
550 means, you do not have sufficient permission and SELINUX may be the reason.
You can check it, just disable the selinux for a moment and try if your job is successful.
If you are confirmed that selinux is blocking it, it is NOT good at all to disable selinux.

You have to remove the error without disabling it.
Try following commands

Also if you are trying to get to home directories, there may be a boolean for that. Will check back soon.

thanks for all recommendations.
The culprit was corrupted files on /etc/vsftpd/ directory. I first noticed ftpusers file has right size. But when i open it up (cat it), nothing but 2 blank lines. I ended up to restored the /etc/vsftpd/ directory.
This server went down hard due to hardware problem. I have found several corrupted files.
Thanks.
