Hello,

I'm back with another DA question:

Is it possible to create a setup of hierarchically chained DAs? I  
tried a following example:

Computers: A,B,C,D,E

A runs a 'master' DA. It is not informed about any other DAs  
(passiveDADetection = true, activeDADetection = false)
B runs a 'sub' DA. It is informed about A (DAAddresses = A,  
passiveDADetection=true, activeDADetection=true)
C runs a 'sub' DA. It is informed about A (DAAddresses = A,  
passiveDADetection=true, activeDADetection=true)

A, B and C run in different subnets and no multicast is possible  
between A and B, A and C, B and C.

D runs as an SA. It is not informed about the existence of the B DA.  
It can discover it through multicast, since it sits in the same  
network as B.
E runs as an SA. It is not informed about the exsitence of the C DA.  
It can discover it through multicast, since it sits in the same  
network as C.

I publish now a service on E and on D.

I fail to discover the service published on D on E and I fail to  
discover the service published on E on D.

If I try to discover a directory-agent on E, I get C only.
|f I try to discover a directory-agent on D, I get B only.
(This might be ok, I don't know).

It seems to me, however, that service registrations are only  
delivered to the 'sub' DAs from their SAs within the same subnet.
It seems that the 'master' DA on A does not see the publications and  
also does not relay them forward.

Maybe somebody from the expert group could help me out

- telling if a hierarchical DA setup is at all possible
- how to create a hierarchical DA setup

Also, if I configure multiple DAs in one SA, are services published  
to both of them or only to an 'elected' primary DA?

Thanks for your help in advance
Johannes Gutleber
