I'm having issues using the membership.createuser method. My code is below, I get a null exception as runtime. Any help is greatly appreciated.
Dim username As String = userNameTxt.Text
Dim password As String = passwordTxt.Text
Dim email As String = emailTxt.Text
Dim status As New MembershipCreateStatus
Dim blank As String = ""
Dim provider As MembershipProvider
Dim providerUserKey As New System.Object
Dim user As MembershipUser
user = provider.CreateUser(username, password, email, blank, blank, True, providerUserKey, status)
you need concrete implementation of MembershipProvider abstract class
you can either create your own or use existing one. You also need to set it in web.config:
<connectionStrings>
<add name="MySqlConnection" connectionString="Data Source=MySqlServer;Initial Catalog=aspnetdb;Integrated Security=SSPI;" />
</connectionStrings>
<system.web>
...
<membership defaultProvider="SqlProvider" userIsOnlineTimeWindow="15">
<providers>
<clear />
<add
name="SqlProvider"
type="System.Web.Security.SqlMembershipProvider"
connectionStringName="MySqlConnection"
applicationName="MyApplication"
enablePasswordRetrieval="false"
enablePasswordReset="true"
requiresQuestionAndAnswer="true"
requiresUniqueEmail="true"
passwordFormat="Hashed" />
</providers>
</membership>
http://msdn.microsoft.com/en-us/library/ff648345.aspx
then you can use Membership.CreateUser, no need to create instance, it's static
it has also a property for default membership provider set in web.config: Membership.Provider
Use the shared methods on the Membership class. You will have to configure the membership provider to use in your web.config file.
Then it's simply:
Membership.CreateUser(username, password, email, blank, blank, True, providerUserKey, status)
For details on how to configure your membership provider, refer to msdn Memberhip doc
Dim provider As MembershipProvider
then
provider.CreateUser(..
provider is null as you haven't actually created a new instance
you should be using
System.Web.Security.Membership.CreateUser

I want to implement user profile, so other users will be able to see it.
How can I get profile info about a particular user by it's id in asp.net mvc3??
This is (in a nutshell) how you would implement the default profile provider.
In your web.config, add
<profile>
<providers>
<clear/>
<add name="AspNetSqlProfileProvider"
type="System.Web.Profile.SqlProfileProvider"
connectionStringName="ApplicationServices"
<!--same connection string as the membership provider-->
applicationName="/"/>
</providers>
<properties>
<add name="FirstName" type="string"/>
<add name="LastName" type="string"/>
<!--...or whatever profile properties you want/need-->
</properties>
</profile>
Then you can assign values to the profile properties
ProfileBase profile = ProfileBase.Create(userName);
profile["FirstName"] = "John";
profile["LastName"] = "Smith";
And read the values
string firstName;
string lastName;
ProfileBase profile = ProfileBase.Create(userName);
firstName = profile["FirstName"] as string,
lastName = profile["LastName"] as string,
I have a simple create user wizard and custom membership provider which was taken from here
Now I am following this tutorial by scott Mitchell and creating new user using wizard and able to send email by setting Disable create property user to "False" so that whenever user recieves the activation link he needs to click that and verifies his account.
Now the problem is when he creates new user it is working fine and when he tried to login immediately he gets message that he needs to ativate the link first in order to login.
And after registration he gets email and when he clicks the link it gives me error that there is no user in the database.
As you can see below that user gets activation link
When the user tried to click it he gets that he is not found in the database
And if i check in the administration tool If I check the user is available without a tick beside it.
Here is my web.config:

If userInfo Is Nothing Then

Membership.UpdateUser(userInfo)
'Display a message

End If
End If
And here is the database screenshot:
#Tim and Baldy-I have finally got working but not with UserID.I don't know what's wrong with the GUID and I tried it with username and it's working perfectly.
So if any modifications with the GUID please let me know.
You are passing a guid type to the GetUser method of the Membership class.
UPDATE Have tested this now. Passing a GUID does call the correct overload - GetUser(object providerUserKey). So this answer is not relevant.
How can you be sure that this is being inferred to the correct overload at runtime?
GetUser has both string and object single parameter overloads, therefore it would make sense to pass the guid in as an object so you are explicitly stating which overload you want to call.
The framework may be calling ToString() on your guid, which would invoke the overload that looks up the username rather than the provider key.
Not at a computer right now, but it should go like this...
Dim key as new object()
'put the guid in the object type
key = Userid
Dim user = Membership.GetUser(key)
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, "MyDomain\MyGroup") Then
Dim UserExists As Boolean = True
End If
When trying that code, I got the above-mentioned error. So I plugged in the roleManager tag in my Web.config like so:
<roleManager enabled="true" cacheRolesInCookie="true" defaultProvider="ActiveDirectoryMembershipProvider" cookieName=".ASPXROLES" cookiePath="/" cookieTimeout="480" cookieRequireSSL="false" cookieSlidingExpiration="true" createPersistentCookie="false" cookieProtection="All" />
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.
Any help would be greatly appreciated.
Thanks,
Jason
Look into this page:http://msdn.microsoft.com/en-us/library/ff648345.aspx
You need something like this in your webconfig specifying where the default role provider points to
<connectionStrings>
<add name="ADConnectionString"
connectionString=
"LDAP://domain.testing.com/CN=Users,DC=domain,DC=testing,DC=com" />
</connectionStrings>
<system.web>
...
<membership defaultProvider="MembershipADProvider">
<providers>
<add
name="MembershipADProvider"
type="System.Web.Security.ActiveDirectoryMembershipProvider, System.Web,
Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"
connectionStringName="ADConnectionString"
connectionUsername="<domainName>\administrator"
connectionPassword="password"/>
</providers>
</membership>
...
</system.web>
I ended up using this:
Private Function ValidateActiveDirectoryLogin(ByVal Domain As String, ByVal Username As String, ByVal Password As String) As Boolean
Dim Success As Boolean = False
Dim Entry As New System.DirectoryServices.DirectoryEntry("LDAP://" & Domain, Username, Password)
Dim Searcher As New System.DirectoryServices.DirectorySearcher(Entry)
Searcher.SearchScope = DirectoryServices.SearchScope.OneLevel
Try
Dim Results As System.DirectoryServices.SearchResult = Searcher.FindOne
Success = Not (Results Is Nothing)
Catch
Success = False
End Try
Return Success
End Function
Worked like a charm when this was in my web.config:
<authentication mode="Windows"/>
<roleManager enabled="true" cacheRolesInCookie="true" defaultProvider="AspNetWindowsTokenRoleProvider" cookieName=".ASPXROLES" cookiePath="/" cookieTimeout="480" cookieRequireSSL="false" cookieSlidingExpiration="true" createPersistentCookie="false" cookieProtection="All" />
How do I access the default SqlProvider in a DAL? I've only ever done this before from webforms.
With the following
using System.Web.Security;
....
SqlRoleProvider roleProvider = new SqlRoleProvider();
string[] roles = roleProvider.GetAllRoles(); //for example to get all role names
EDIT
To configure your application to use the SqlRoleProvider you'll need to add the following under the <system.web> section of your web.config file.
<roleManager enabled="true" defaultProvider="SqlRoleManager">
<providers>
<add name="SqlRoleManager"
type="System.Web.Security.SqlRoleProvider"
connectionStringName="MyConnectionStringName" //change this to the name of your connection string
applicationName="MyApplication" />
</providers>
</roleManager>
I would like to know how I can verify a user's credential against an existing asp.net membership database. The short story is that we want provide single sign on access.
So what I've done is to connect directly to the membership database and tried to run a sql query against the aspnet_Membership table:
private bool CanLogin(string userName, string password)
{
// Check DB to see if the credential is correct
try
{
string passwordHash = FormsAuthentication.HashPasswordForStoringInConfigFile(password, "SHA1");
string sql = string.Format("select 1 from aspnet_Users a inner join aspnet_Membership b on a.UserId = b.UserId and a.applicationid = b.applicationid where a.username = '{0}' and b.password='{1}'", userName.ToLowerInvariant(), passwordHash);
using (SqlConnection sqlConn = new SqlConnection(ConfigurationManager.ConnectionStrings["LocalSqlServer"].ConnectionString))
using (SqlCommand sqlCmd = new SqlCommand(sql, sqlConn))
{
sqlConn.Open();
int count = sqlCmd.ExecuteNonQuery();
return count == 1;
}
}
catch (Exception ex)
{
return false;
}
}
The problem is the password value, does anyone know how the password it is hashed?
if you have two asp.net apps on the same IIS server, you can do SSO like this. I asked this question and answered it myself.
here
Once you have both apps pointing at your asp_membership database by placing the following in the system.web section of your web config
<authentication mode="Forms" />
<membership>
<providers>
<clear/>
<add name="AspNetSqlMembershipProvider"
type="System.Web.Security.SqlMembershipProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"
connectionStringName="membership"
applicationName="/"
/>
</providers>
</membership>
<roleManager enabled="true" />
make sure both have the same applicationname property set.
I was using IIS 6 so I configured it to autogenerate a machine key for both applications. Because both of these applications live on the same machine the key would be identical, this is the critical part to making the SSO work. After setting up IIS the following was added to my web.config
<machineKey decryptionKey="AutoGenerate" validation="SHA1" validationKey="AutoGenerate" />
That was all there was to it. Once that was done I could log into app1 and then browse to app2 and keep my security credentials.
The problem is the password value,
does anyone know how the password it
is hashed?
Yes - you do! Check your web.config file for something like this:
<membership defaultProvider="MembershipSqlProvider"
userIsOnlineTimeWindow="15">
<providers>
<add name="MembershipSqlProvider"
type="System.Web.Security.SqlMembershipProvider, System.Web,
Version=1.2.3400.0, Culture=neutral,
PublicKeyToken=b03f5f7f11d50a3a"
PasswordFormat="Hashed" />
</providers>
</membership>
The PasswordFormat is what you are looking for. It can have the following three values:
Clear
Encrypted
Hashed
And, Microsoft sets the default value to Hashed for PasswordFormat.
Why don't check it automatically via System.Web.Security.Membership.ValidateUser() ?
