if you want this done on a single server, its not hard. I have it
setup in my company like this. Basicaly each application uses two
cfapplication tags, one with name MAIN first and second with the name
of the app. After the first one I do a check to see if the user is
"logged in" to MAIN, if not I redirect them to a central /login dir
which uses a cfapplication tag with name MAIN. After login they are
redirected back to the app. At this poit the test for being logged in
to MAIN passes and then the second cfapplication tag kicks in. Then I
test to see if the user has access to the local app. THat's it in a
nutshell. If all your apps on one server are CF based, this can work
fine and dandy. Here is an example...note each app has a login subdir
that does the auth stuffs. This would be the application.cfm from it.
<!--- begin editable area here --->
<cfset appurl = '/path/back/to/the/local/app/login/><!--- this MUST be
the URL to your app...absolute path is required --->
<cfset message = 'My app name'/><!--- optional: show message on
CENTRAL login page --->
<!--- end editable area here --->
<!--- do not edit this --->
<cfapplication name="main" sessionmanagement="Yes"
sessiontimeout="#CreateTimeSpan(0,2,0,0)#">
<cfparam name="session.main.globalauthorized" default="0" />
<cfif session.main.globalauthorized NEQ 1>
<cflocation
url="/login?appurl=#URLEncodedFormat(appurl)#&message=#URLEncodedFormat(message)#"
addtoken="no" />
</cfif>
<!--- make local copy of session data to transfer to other local
session scope --->
<cfset variables.foo = duplicate(session.main) />
<!--- end do not edit this --->
<!--- local session data stuffs setup session here...note this session
supercedes the above--->
<!--- begin editable area here INSERT YOUR APPLICATION NAME HERE--->
<cfapplication name="foo" sessionmanagement="Yes"
clientmanagement="Yes" sessiontimeout="#CreateTimeSpan(0,0,20,0)#">
<!--- do not edit this --->
<cfset session.user = duplicate(variables.foo) />
<!--- end local session data stuff --->
<!--- end do not edit this --->
