I find the solution:
1. Log in your server by ssh;
2. Log to mysql, typing: mysql -u root -p;
3. Insert your mysql root password (dont know? stop this and type: sudo nano /root/passwords.txt and you see your root mysql password, start again from step 2);
4. type: use sentora_proftpd;
5. type: select * from ftpdusers; // this will list all your ftp accounts, find the id of the user will be changed.
6. type: update ftpusers set userid = 'ftp_username_here' where id = 'username_id_here';
Done! Now you can login in your ftp without 'zadmin_' prefix.
I see in the sentora panel the username continue with 'zadmin_' prefix, but is working fine.
Please be careful with this operation, this is not recommended, just change the username if you know what you are doing.
