I understand that username could be a problem but we do also have the IP address of the workstation that is making the request. So the other way we thought this could possibly work was:

1) Extract the IP address from which the request originates

 

2) Reverse lookup the address to retrieve the hostname

 

3) Lookup the machine's group in the AD

 

4) Choose the pool based on the machines group

 

 

 

There are two accounts in the AD, one for the machine and one for the user. Essentially the machine is the thing that is capable of dual screen and not really the user so checking the machine's group instead of the user is a little more correct.

 

 

 

Extracting the source addr is not a problem and easily achievable but I'm not sure its possible to:

 

 

 

1) do a DNS lookup in the iRule

 

2) do an search for the group, using either LDAP, SMB or potentially even Radius.

 

 

 

Are these things two things possible?

 

 

 

thanks
