second logon page while already in Webtop portal

Hello,

 

I want to know if it's possible to generate a new logon page after user clicks on an application link while already connected in F5 Webtop portal. The user has already logged into the Portal and I want to capture new credentials and do SSO for some applications that are not authenticating with the same database that point to the initial F5 Portal logon page.

 

Let say for instance that the initial logon page point to an LDAP directory for authentication and some other applications into the Portal use an AD to authenticate users.

 

thanks for your help
