Default Issue with custom membership provider

I have am using the custom membership provider and I had it working fine. With the following enty in webcofig

 <membership defaultProvider="CustomizedProvider">
      <providers>
        <add name="CustomizedProvider"
             type="System.Web.Security.SqlMembershipProvider"
             connectionStringName="LocalSqlServer"
             minRequiredPasswordLength="5"
             minRequiredNonalphanumericCharacters="0"
             requiresQuestionAndAnswer="false"/>
      </providers>
    </membership>

I next tried to change the passwordformat to encryptyed and replaced the above membership with the following (adding a encryption key)

 <machineKey validationKey="D61B3C89CB33A2F1422FF158AFF7320E8DB 8CB5CDA1742572A487D94018787EF42682B202B746511891C1 BAF47F8D25C07F6C39A104696DB51F17C529AD3CABE"
                decryptionKey="FBF50941F22D6A3B229EA593F24C41203DA 6837F1122EF17" />



    <membership defaultProvider="CustomizedProvider">
      <providers>
        <add name="CustomizedProvider"
             type="System.Web.Security.SqlMembershipProvider"
             connectionStringName="LocalSqlServer"
             enablePasswordRetrieval="true"
             passwordFormat="Encrypted"
             minRequiredPasswordLength="5"
             minRequiredNonalphanumericCharacters="0"
             requiresQuestionAndAnswer="false"/>
      </providers>
    </membership>

This runs fine on my localhost and I can login without any problem.

When I run this to my host server I get the following error.

Configuration Error
Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.

Parser Error Message: The entry 'CustomizedProvider' has already been added.

Source Error:


Line 95: <membership defaultProvider="CustomizedProvider">
Line 96: <providers>
Line 97: <add name="CustomizedProvider"
Line 98: type="System.Web.Security.SqlMembershipProvider"
Line 99: connectionStringName="LocalSqlServer"

Help with this issue would be greatly appreciated.
Thanks

Hi Calcado,
Sorry I can't be of an yhelp but I wonder, how's your setup? I'm trying to get the custom membership provider working but I don't understand where to find the SELECT statement in the custommembershipprovider.cs file. Could you please paste yours?

Mine looks like below (copied from support.microsoft.com). Thanks!

Pettrer

Here's the code that is in the .cs file (I'm trying out the ValidateUser method):

using System;

using System.Web;

using System.Data;

using System.Configuration;

using System.Collections;

using System.Web.Security;

using System.Collections.Specialized;

using System.Data.SqlClient;

class CustomMembershipProvider : MembershipProvider

{

public override void Initialize(string name, NameValueCollection config)

{

// Verify that config isn't null


if (config == null)

throw new ArgumentNullException("config");

// Assign the provider a default name if it doesn't have one

if (String.IsNullOrEmpty(name))

name = "AspNetCustomMembershipProvider";

// Add a default "description" attribute to config if the
// attribute doesn't exist or is empty

if (string.IsNullOrEmpty(config["description"]))

{

config.Remove("description");

config.Add("description", "Custom SQL Provider");

}

// Call the base class's Initialize method

base.Initialize(name, config);

}

public override bool ValidateUser(string username, string password)

{

SqlConnection cnn = null;

SqlCommand cmd = null;

bool userExists = true;

try

{

cnn = new SqlConnection();

cnn.ConnectionString = "myConnectionString";

cnn.Open();

string selectQry = "Select query for username and password";

cmd = new SqlCommand(selectQry, cnn);

SqlDataReader rdr = cmd.ExecuteReader();

if (!rdr.Read())

userExists = false;

}

catch (Exception ex)

{

throw ex;

}

finally

{

cmd.Dispose();

cnn.Close();

}

return userExists;

}

public override MembershipUser CreateUser(string username, string


password, string email, string passwordQuestion, string

passwordAnswer, bool isApproved, object providerUserKey,

out MembershipCreateStatus status)

{

SqlConnection cnn = null;

SqlCommand cmd = null;

MembershipUser newUser = null;

try

{

cnn = new SqlConnection();

cnn.ConnectionString = "myConnectionString";

cnn.Open();

string insertQry = "Prepare the Insert query...";

cmd = new SqlCommand(insertQry, cnn);

cmd.ExecuteNonQuery();

// Right now I am giving default values for DateTime
// in Membership constructor.

newUser = new MembershipUser(

"AspNetCustomMembershipProvider",

username, null, String.Empty, String.Empty,

String.Empty, true, false, DateTime.Now,

DateTime.Now, DateTime.Now, DateTime.Now,

DateTime.Now

);

status = MembershipCreateStatus.Success;

}

catch (Exception ex)

{

status = MembershipCreateStatus.ProviderError;

newUser = null;

throw ex;

}

finally

cmd.Dispose();

cnn.Close();

}

return newUser;
