Jerry,
Out of the box, the behavior is that you need to know to login to B. However, you can create a simple ASP based redirector that will lookup a user's home server and redirect to it. The following tech tip for Unity 3.x can be applied to Unity 4.x as well with slight modifications that I detail below:
http://www.cisco.com/en/US/partner/products/sw/voicesw/ps2237/products_configuration_example09186a00800c52e5.shtml
The code in the tech tip is missing some comment markers and a simple copy/paste won't work - you'll need to add comment markers in the right places - but that should be obvious when you read through it. However, a copy of this code may also be available on your Unity server in the /web/AA directory as GlobalAA.asp. The web/aa directory is obsolete in Unity 4.x but is still bundled in the installer. Please do not try to point your browsers to AA, just pick up the GlobalAA.asp file :) Now follow these steps:
1. On your Unity servers, create a directory: \cscoserv\ciscopca\redirect
2. Copy GlobalAA.asp as default.asp to the above directory
3. Modify the redirect statement in default.asp to this:
Response.Redirect "http" & "://" & strServer & "/ciscopca"
4. Launch 'Internet Services Manager', find 'Default Web Site', right click and select new 'Virtual Directory'.
5. In the 'Virtual Directory Creation Wizard', set the following:
Alias: 'cpca' (or whatever you want it to be)
Directory: \cscoserv\ciscopca\redirect
Access Permissions: Read and Run scripts
6. Find 'cpca' under 'Default Web Site', right click and select 'Properties'
7. Go to the 'Directory Security' tab and make sure 'Anonymous Access' is UNCHECKED and 'Integrated Windows Authentication' is CHECKED.
That should do it. The global URL to get to CPCA would be /cpca, where follows the same conventions mentioned in the TechTip.
The TechTip will be cleaned up and a new version will be published on CCO when its ready.
