BSP - UserId and Password for Internal Users - Anonymous for other users

Question

Hello,
We developed an application via BSP's. This application can be accessed by two kind of users.
1. External Users, with should access the page without using a userId and password.
2. Internal Users, they will have more authorisation and need to specify their userId and Password.
How can we accomplish this? I tried internal aliases, but can't get it to work properly.
In the first service 'zbsp' I didn't specify a userId and password in sicf.
Then I created an internal alias 'zbsp' referring to this 'zbsp'. In this alias I specified a userId and Password, but the system still asks for a userId and Password. (and after logging in the system gives the following error: The application name in URL .../bc/bsp/sap/zbsp2/uat_report.htm is invalid.)
What did I do wrong? Or are there other ways to accomplish this?
Greetings,
Bart

Take a look at the following mesaages that discussed the whole SSO and SSO2 ticket logins.
As for a way to handle the two different login types. Well first and formost - active the SSO Tickets on your system.  Set your BSP up for that.
Then create a new starting page with an alias to the pöublic section for BSP's in your system. On this page make two links.
For your external users - one that redirects to your BSP passing the user and password in the url for the "read only external user" - that's the sap-user=name here&sap-password=passwordhere.
For your internal people give them simply the link to the BSP which when they click it will see no user name and password and redirect them to the BSP login.
Make sure you setup the BSP login according to SAP note 517860 and follow the instructions from http://help.sap.com/saphelp_nw04/helpdata/en/1d/13c73cee4fb55be10000000a114084/frameset.htm using the supplied SYSTEM_PUBLIC)
It's a bit basic but it works, we do it
Oh and setting up the system for the SSO (transaction sso2) is very very simple!!
