We are attempting to establish a dynamic Security Level Rule that applies when the hostname of a client is found in a dataset.

This Rule is working:

```auto
lookup(
//dataset
{[provider]IGN/DBCache/BMS_DATA/ClientProperties/databaseValue}
,//lookupValue
'clientHost'
,//noMatchValue
false
,//[lookupColumn]
'host'
,//[resultColumn]
'autoTechnicianLogin')

```

But when we try to replace the static string 'clientHost' with {[System]Client/Network/Hostname} or {session.props.host} it does not work.

Okay, in this case, I would have to write down all hostnames manually. Is there an option to retrieve these names from a database or a tag?
