How to limit users in proftpd

Hello,

I would like to limit the number of users connecting to my server via ftp.
Can someone please help me out...

Have these ftp users:: user1, user2, user3

Limit number of connections from all users except one user, to 1.
ie, only 1 connection should be possible at a time for user1 <- (case 1)
and
only 1 connection should be possible at a time foruser2
and
user3 should be able to make more than 1 connection at a time <-(case 2)

Version : proftpd-1.2.10

I tried MaxClientsPerUser for case1, but it seems only 1 user can ftp to the server at a time.
My /etc/proftpd.conf is given below.

Someone please help me out... Thanx in advance.
