RDP Persistence - irule, can it be done

I have a scenario where i have connections coming into a Virtual server on an F5 (v10.2). Source IP address is always the same, i am load-balancing to 16 Terminal Servers (we aren't/can't use Session Directory due to other reasons, nor are clients providing their user name until they have connected).

 

 

Load balancing based on least connected member is working perfectly, however I cant seem to get persistence to work, without all connections going to the same TS server.

 

 

I was wondering if there is any way that reliable persistence could be done maybe by using an iRule.

    Thanks for your reply, I have read this doc previously, however our TS environment doesn't use a session directory server, which is where my problem is.

    you can persist on username, but you have to make sure the clients are configured to send the username (better to be user@domain than domain\user so you get more unique characters) otherwise the username will not be viewable.

    I don't think I'm going to be able to get clients to send credentials, which i guess is going to limit my options when it comes to persistence.
