Remove active connections from backup system after return to normal

Hi,

 

 

I am using my BigIP in front of a set of LDAP Servers. I have the servers in priority groups, and obviously only want traffic to hit the lower priority when there is a failure. However, LDAP clients tend to make very long, persistent connections to servers and unfortunately will keep these connections indefinitely to the backup (lower priority) boxes even if a higher priority returns to service since the connection is "active". Any suggestions on a good way to sever these connections in the event of a higher priority becoming available again?

 

 

Thanks in advance,
