What's portal for?

[Mansour <ma...@yahoo.com>]

Helloevery one:

I read a bit on the portal web site and what it can do. However, I am 
not certain if it has what I need. I need a security gate for different 
web applications. The gate can be configured to allow users and groups 
access to the applications. This can be achieved through admin  
webpage.  Users and groups access  can be stored in ldap service. For 
example, if I have a new application (app1), I can deploy it as a *.war 
file and setup the access through the admin page.
I was about to start writing my own, but decided to look around to see 
if there anything has been done about this. Can anyone give me an advice?

Thank you.
