we setup dnn as main site, going to mingle our stuffs into it

the 1st thing is the login, we managed to work out our own/custom login, also using ASP.NET Membership

the issues are:

1. we worked out the login module and logic, tested good. using System.Web.UI.WebControls.Login

but we noticed somehow upon postback/login, the usercontrol will have 2nd invocation as non-postback, so postback result is not shown.

is this the ASCX behavior under DNN module?

2. our custom login is to do with our custom app, should we reflect it's login status onto the DNN authencation login level? though our login is diff db.

or should we keep separate our custom login from the dnn login?

as our custom login does not mean the user can edit/manage the CMS, it just to browse/use our custom app.

we still need the CMS login, so our other dept can do their CMS later online.
