Check To See If A Given Username Is In A Certain Role?
Jul 6, 2011
I have an ASP.NET application on our company's intranet. And a funky security requirement.
I need to check to see if a given username is in a certain role. I cannot use
Page.User.IsInRole("MyDomainMyGroup")
because
Page.User.Identity.Name
Returns an empty string. Because of some lovely specifications for this program, I have to keep anonymous access enabled in IIS. Seems to rule out any page.user.identity stuff.
So I did find a way to (at least) get the current user (from System.Environment.UserName), but I need to bounce it against the domain group to see if they're in it. Or, better yet, get a list of users within a given domain so I can check myself. Something like...
Dim UserName as String
UserName = System.Environment.UserName
If User(UserName).IsInRole("MyDomainMyGroup") Then
[Code]....

In my VS solution, I have two projects.One for the Web Interface, other for DataAcess and BusinessLogic. I know I can check if the currently logged-on user is Employee in Web Interface project like this from the code behind:
Dim isEmployee = User.IsInRole("Employee")
The problem is that I have a Class call UserManagement in my the DA and BL project which I want to check the currently logged-on user role also. I can't use Dim isEmployee = User.IsInRole("Employee") because it doesn't have aspx page.
What do I need to do to check the user role in my custom class?

I have an asp.net web forms application that uses asp.net membership and URL Routing.Because of the way Roles work, i cant put an "AND" or "OR", etc. in the allow/deny tags of the web.config file that resides in each folder.This is a business website that that is being ported from a vb.net win forms project that contianed many apps. (The win forms project have a custom authentication system.)The web app is structured in a way to mimic the desktop suites and a folder was created for each app.There are also common folders where any user of any app can generate a report.

I am working on a code for a chat client/server and I have it all working, I can connect and chat locally and global. The problem I am having is that when someone just hits the X in the corner to exit it crashes my server as well as the fact that if someone wants to they can make their username the same as someone elses.

I've created a new datasource dtsLogin containing an ID, username and password. my problem is how can you check if the username & password typed in the textbox are the same as the one on the Access database? I thought maybe using a rowfilter but I'm not that good in ADO.net.

I have a chat server / client system running, but I want users to authenticate with my vBulletin forum database.I don't want the client to do it, because it is possible to fake the 'successful login' and connect with a fake username. I want to send the username and password details to the server, and make the server check it with the local vBulletin MySQL database for the username and password.Is there a way to do this? To my knowledge vBulletin has a username and a password entries in the database which is salted, and the salt varies from user to user.

My intent is to have the code - on a button.click event - check the Username and Password fields and return an error depending on which is wrong. Or if both are wrong, return a different error message. I've set the username as parts and the password as parts (still learning how to use external authentication). [Code]

I'm trying to create a routine in my asp.net's main page that will see if the current user is a member of a Windows domain group. The site is hosted in IIS and is visible through our intranet.
GlenFerrieLive listed this code (which I'd like to use) in an earlier post:
UserName = System.Environment.UserName
If Roles.IsUserInRole(UserName, "MyDomainMyGroup") Then
[Code]....
Problem is, now I'm getting the configuration error 'Default Role Provider could not be found'.
How can I get around this? I just need to see if the current user exists in a specific domain group.

This desktop app written in VB.Net within VStudio 2008 fails when one of our "power users" tries to run the program: Select permission denied on object 'AcctLogon', database 'MDS', owner 'dbo'. The author of the app is out for a few weeks and I am the "fixer" while she's out. Both of our logins for SQL have permissions for db_owner in the MDS database but our user does not. The user has a Windows user login for this instance of SQL. This login has permissions for the public role only in the MDS database.

I am curious as to the proper technique to use SQL Server's AppRole with a LINQ to SQL Class. I understand I have to establish the intial connection with no connection pooling. However, do I simply call the SQL stored procedure sp_setapprole using standard LINQ before executing any of my methods that interact with the database, or is there a better way to enable and use AppRole within the LINQ to SQL class?

Iv'e been away from Visual Basic for the past 3 or 4 years so I am a bit vague on the details that I am looking for.
I got myself my first programming job at the company that I work for and I start Monday.
The company has little programming knowledge (well I assumed this as they said they do not have a dedicated programming IDE at my interview) and relies on ad-hoc VBA scripts to perform necessary processing on data. This is all fine and I can deal with that but there is a project that I wish to work on and I think a standalone dedicated application would be much better than extending Excel with VBA.
Now after being with the company for 10+ years, I know they are conservative at spending money so asking them to buy Visual Studio is not really an option so I'm going to suggest that instead of using VBA, I will design an application using Visual Basic Express.
All I need to know is, if there are any kind of limitation to database accessing with the express editions? (Iv'e only ever used OLEDB connected to small MS Access files) I do not know what type of database the company uses yet, but I do know they use ODBC to connect to it, and rely on Sage to do 90% of their work.

I'm creating a custom Role provider based on the ASP.NET Role provider. I have 3 tables. One for Users, one for Roles, one for UsersInRoles.The Users table has no password column because the users are authenticated with ActiveDirectory. That's my approach so far. I can't get the cusstom Role Provider to work, anyone has the same situation like me. How do you make a custom Role provider works with AD?
