Why not use the<a href="http://msdn.microsoft.com/en-us/library/yh26yfzy.aspx" rel="ugc nofollow"> built-in role membership provider</a> that comes with ASP.NET? Once this is in place it's as easy as using <i>HttpContext.Current.User.I<wbr />sInRole(&quot;M<wbr />yRole&quot;)</i> to check for permission.
</div>


<div>
The built in membership provider doesn't allow for groups and roles within groups, but you could handle that yourself with a specified role naming convention e.g.<br />
<br />
Group1-Member<br />
Group1-Admin<br />
Group2-Member<br />
Group2-Admin<br />
<br />
Then you can assign to users as you like, and implement the checks in the page as you like.

@brutaldev: roles provider is not enough for what's required. To be clear, I need, sort of, 4 providers... Membership, group, roles, and permissions...<br />
<br />
@dale_burrel: I could have settled down with what you have suggested but thhe permissions are really getting on the way.. is ithere a way to implement a custom &quot;provider&quot; in which I would probably call permissions provider and will work together with the roles provider? Or maybe implement two instances of roles provider 1 for your group_role suggeztion Nd the other for permission?
</div>


<div>
You can certainly implement custom providers... I've never done it so I can only offer the MS documentation e.g. <a href="http://msdn.microsoft.com/en-us/library/8fw7xh74.aspx" rel="ugc">http://msdn.microsoft.com/en-us/library/8fw7xh74.aspx</a>
</div>


<div>
@dale_burrell: if I implement one, is it possible to have 2 role providers active in one application?

Hi,<br />
I need to implement a somehow complex membership and authorisation. The requirements include a the normal authentication... But each user can be a member of 1 or more group. And their role per group may differ. Eg. User1 can be a member of group A in which he is an administrator... And be a member of group B but with a role of jus a regular user. <br />
Apart from that, each member may have different &quot;permissions&quot; that they can do something like the NT logins.<br />
I have reasearched that I can probably use azman... Is azman good? Is there an alternative approach like a modified role provider? Is there such as group provider?

Hi,

Apart from that, each member may have different "permissions" that they can do something like the NT logins.

Asp.net complex membership implementation

The successor to Active Server Pages, ASP.NET websites utilize the .NET framework to produce dynamic, data and content-driven web applications and services. ASP.NET code can be written using any .NET supported language. As of 2009, ASP.NET can also apply the Model-View-Controller (MVC) pattern to web applications

ASP.NET

The .NET Framework is not specific to any one programming language; rather, it includes a library of functions that allows developers to rapidly build applications. Several supported languages include C#, VB.NET, C++ or ASP.NET.

.NET Programming

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).
