it might help if you explain a bit better what you want, we can't read minds here (and we don't want to ... usually ...)
to start with SSRS, you mean SQL Server Reporting Services?
then you say implement, what do you mean with implement, you want to load balance two SQL Server Reporting Services servers on a F5 BIG-IP running 11.6?
then you mention it requires authentication, how exactly, do you need to authenticate before you can access the SQL Server Reporting Services? or do the SQL Server Reporting Services have to authenticate against something?
so authenticating with AD, but again what exactly. if you are wondering how to do the authentication of SQL Server Reporting Services with AD, then a microsoft forum is probably a better place.
what is asking for a uri? please provide a screenshot or such.
