Is there an IsInGroup Function

[David Stephen]

I would like to check if a user on an ASP.net web form is in a particular group.

I have Forms authentication turned on and need to check programitacilly if a user is in a group or not to allow access to various fnctions.

There is a User.IsInRole function but I always get false for just the Group Name or Domain/Group Name.

Is a Role different to a Group?

Any samples around like this?

Also, is there a way to identify all the groups in a domain via WMI or something?

Thank you

David

User.IsInRole exists in web forms and can be used as

User.IsInRole("Domain\Group")

However, if the Group is predefined by Windows then you need to use
BUILTIN\Group

I have seen code that actually checks security like

Dim wp As New System.Security.Principal.WindowsPrincipal(CType(User.Identity, System.Security.Principal.WindowsIdentity))
wp.IsInRole("Domain\Group")

But I do not know why the difference.

I still can not find out how to get the list of groups on a network.
