Forms Authentication +Active Directory +Roles

Discussion in 'ASP .Net' started by Marty Underwood, Oct 29, 2003.

  1. Okay the subject line explains a scenario I just had to tackle but I am
    looking for a better way.

    The current way:

    1) Use forms authentication.
    2) Query Active Directory and bind to a user object if no exception create
    custom authentication ticket.
    3) But I also needed Role based security within the app. So I used SQL
    server 2k DTS package to get the members of the AD group and then created a
    notification system to the application security administrator about a new
    user if the user was not configured. The security administrator could then
    log into the application and Activate the account. The user is notified when
    they log in whether there account is "not activated", "pending activation".

    What I need to know:

    If there a way I can use AD authentication with forms authentication and
    have role based security without maintaining a seperate db. For example, if
    I had 2 AD groups how would I assign each group to a role.

    Select Case, If/then, hopefully you get my drift.

    The company I work for has a security team that manages all changes and
    account request in AD. So it is difficult sometimes to convince them I have
    4 roles for an application so I need 4 groups whether they be nested or not.

  2. not.

    Marty, I don't understand: what's wrong with treating groups as roles?

  3. Hey John, it's not that there is anything wrong the problem comes when
    determining which groups a person is a member of and then assigning them to
    a role. Keep in mind some of these people may be a member of 20 or 30 groups
    for the organization. I really hate to get the groups, drop groups into an
    array and then for/next through each one to assign a role.

    Alot of overhead I think can be prevented I just can't think of the simplest

    Basically, my question is this, if I have 4 AD groups because I need 4
    roles, how do I assign that person to a role when that person may be a
    member of 50 plus groups.

  4. I haven't done much AD programming, so maybe I'm missing something obvious.
    But how about getting the list of AD groups the user is in from AD and
    putting it into an array and sorting it, and using binary search on the
    sorted array to look up all the AD groups which correspond to your roles?

    Or how about just adding all the AD groups as roles? The ones which don't
    correspond to roles won't hurt anything (except to make the list of roles

    I just don't see much room for doing something much different: you've got
    two lists of "group-like objects". Either they're from the same set and you
    use them as is, or they're from different sets and you need to find the

  5. Long last couple of days, what you say is what I have to do. I was just
    working on 3 different projects at the same time and guess I got my mind
    sidetracked. I thought about a different way and that is to check the
    members of a group against a username and see if that person is a member of
    the group instead checking the groups that person is a member of.

    Thanks for your time
