Serv-u plus is a serv-u plug-in,you can find them everythwhere from the search. which can serve large account with ftp traffic count. many forum use it as private ftp account manager.
when u install serv-u plug-in with serv-u ,u maybe find
Invalid username/password ,incorrent mysqlclient version,please upgrade your client library.
I have solved this error well.
Serv-u Server 6.1 and serv-u plus 1.5 and mysql-5.0.33
first we install serv-u plus as advistion,import tables to DB.
eg: we create database FTP1 and import tables to FTP1,
we grant all privileges to FTP 1 database.
grant all on FTP1.* to user1@’host’ identified by ‘userpass';
UPDATE mysql.user SET Password = OLD_PASSWORD(‘userpass’) WHERE User = ‘user1′;
restart serv-u ,it will work
