Question

Hi Frineds
While trying to open a task in UWL, system shown an message
SSO logon not possible; invalid host name for issuing cookie
Choose "Logon" to continue A dialog box appears in which you can enter your user and password
No switch to HTTPS occurred, so it is not secure to send a password
Plz let me know the reason and how to fix it

SSO logon not possible; invalid host name for issuing cookie
You can do this
(1) Set the security trace level in the ticket accepting system
======================================================
1. Call transaction SM50 (process list):
2. Process -> Trace -> Reset -> Workprocess Files
3. Key combination: F5 (select all), CTRL-Shift-F7 => Dialog box;
4. Set trace level=3 and ONLY(!) check the "Security" component;
  If necessary, you must repeat these steps for each server (see
  transaction SM51), unless you can use a specific server for
  reproducing the error (for example, by excluding the load
  distribution).
(2) Run the webdiagtool as per example 3.
(3) While the webdiagtool is running, please reproduce a failed attempt
to the backend
(4) When the SSO fails, wait a minute and then press return in the
diagtool console so that the resulting traces are picked up
Please check the configuration in portal, use fully qualified domain
name instead of host name.
