DNN ver: 5.6.7

We have a custom module for logging in and registration etc on our portal's homepage. Currently if someone tries visiting a bookmarked link - but they're not logged in - the portal redirects them to the standard, default DNN login module aka the wrong one.

https://mysite.com/Default.aspx?tabid=5688&ctl=Login&returnurl=%2fpreview%2fManage%2fCustomPortalAdministration%2ftabid%2f5688%2fDefault.aspx
&error

I'm not even sure what I need to do, to get users back to our custom login module. Do I need to set a default redirect to the portal homepage? Do I need to set the default login module to our custom login module?

Any help is much appreciated.

In case anyone is wondering, or has the same problems, I commented out a section in the Globals.vb code that checks to see if the login module has a FriendlyName of "Account Login" and just had the function return "True." 

It's a core code modification/hack, but it works.

Public Function ValidateLoginTabID(ByVal tabId As Integer) As Boolean
            Dim hasAccountModule As Boolean = Null.NullBoolean
            'For Each objModule As ModuleInfo In New ModuleController().GetTabModules(tabId).Values
            '    If objModule.ModuleDefinition.FriendlyName = "Account Login" Then
            '        'We need to ensure that Anonymous Users or All Users have View permissions to the login page
            '        Dim tab As TabInfo = New TabController().GetTab(tabId, objModule.PortalID, False)
            '        If TabPermissionController.CanViewPage(tab) Then
            '            hasAccountModule = True
            '            Exit For
            '        End If
            '    End If
            'Next
            hasAccountModule = True
            Return hasAccountModule
        End Function
