Don't worry, It is simple. I have several I use.

 

 

I started out just with LDAP (tcp/389) and LDAPS (tcp/636) because there were some ldap based apps that wanted to access the AD servers and they didn't cope very well with servers not being available.

 

 

However it soon became apparent that some that needed he rest of the AD services ALSO needed this treatment. So I just added a port 0 VS with the LDAP and LDAP VS's and used the same LDAP monitor. Then added source IP persistence across a virtual address and let it go. Works like a charm. No special magic or even an iRule required.
