Allow FTP access to a /directory/subdirectory/ using a FTP users datagroup

Hi,

 

I need to create an iRule to provide FTP access to a /directory/subdirectory based on username. We have a datagroup created where we have integrated usernames-passwords and path.

 

I have started building it, but not sure if I am in the right direction:

 

when FTP_REQUEST { set match_list [class match -value [username] equals $static::FTP users]

 

Regards,
