[Proftpd-user] single user login to multiple virtualhost with one public ip

[Laszlo F. <bla...@kt...>]

Hello!

I want to create an ftp server with separated (,but sometimes shared) 
contents for many users, and users sometimes can login not just to one 
separated content.

Example:
Username  UserPass   Homedir/DefaultRoot
user1         pass1        /ftp1   
user2         pass2        /ftp1
user3         pass3        /ftp1   
user1         pass1        /ftp2
user3         pass3        /ftp2
user4         pass4        /ftp3

etc.

I tried Virtualhost, but it can be another ip or other port, the other 
port can be usable, just I don't want users to memorize port numbers.
So the user can give the ftp server hostname in his username, and the 
proftpd forward the login to te virtualhost, or the port for 
virtualhost? (example username: user1*ftp1)
Maybe can the virtualhost run on the same port and choose it from username?
Maybe can I modify dinamically the users homedir based on the loginname?

And finally can I connect this with ldap authentication?


Thank you very much, blackluck
