Can someone please clarify this licencing question :

We have a dedicated BorderManager server as follows :

NetWare 6.0 SP2 (Free Server Licence obtained from Novell)
BorderManager 3.6 SP2A - 10 Users


Question :
If we want to use the Apache Web Server on this server would we then
need to purchase NetWare 6 User Licences for each web user?

Thanks,

Richard.
