[THIN] Re: Authentication Custom ICA Connection/Application Set

Hi Aleks,
 
A custom connection, if you use the application server's IP adress, ony 
requires access to the server via port 1494. User authentication is done during 
the logon process.
 
An application set also requires the client to be able to enumerate published 
applications. 
 
This means the client will have to be able to "talk" to the XML service (port 
80) on one of the application servers, and, depending on farm configuration, 
also the XML service on the data collector. 
 
The default discovery mechanism for app servers is a DNS lookup on the hostname 
"ica". Otherwise a browser list of app servers will have to be defined for the 
ICA client and this still might still not work if the data collector isn't one 
of the servers visible. 
 
Data collector access aside, it's easy to embed a default browse list into a 
preconfigured client. PN enumeration should then work.
 
An application set also requires authentication, so in your scenario 
passthrough authentication would have to be disabled.
 
regards,
 
Rick

Subject: [THIN] Authentication Custom ICA Connection/Application Set



Hi, 

Our setup: 
NT 4 domain (WINS no DNS) 
W2K Servers 
Metaframe Xpa FR3 

We have some users from another company who are resident in the same building 
as we are. They are on a different VLAN. The networkguru's created a switch 
accesslist which allows them to access 2 of our terminal servers. These TS host 
an application which they need.

We used the Program Neighborhood to create the application set to our farm (we 
tried all types of connection settings: TCP/IP, TCP+HTTP etc). When we opened 
the application set, it tries to connect, nothing happens for a while, followed 
by a "1030 protocol error" or a "The Citrix server is not accepting 
connections" error.

The next thing we tried was a to create a Custom ICA Connection directly to the 
application. Starting this connection directly gave a logon screen and worked 
immediately !!!


That made me wonder why an applicationset to our farm doesn't work and a custom 
does!  It seems that that the application set needs some kind of  "broadcast" 
to connect?

Any ideas on why the applicationset won't work and the custom does.? 

TIA 

Aleks
