Single IP multiple hosts some with ldap auth

Hello
i am very new to F5 devices and I would like to ask question:

I have one ip for example 1.1.1.1 i would like to share it between few domains for example:

when HTTP_REQUEST {
   switch -glob [HTTP::host] {
     host1.dot.com                  { pool Pool1 }
     host2.dot.com                  { pool Pool2 }   

     default                                 { pool Pool1 }
   }
}

It is working ok, but now i need to use LDAP to auth Pool1 and not use LDAP for Pool2, can anyone help how to put it in the configuration ? I have LDAP configured and tested just does not know how to use it with selected pool.

best regards
