I would like to create a sync process between an ADSI table and aspnet Membership using Membership.CreateUser. However, I need to see if a user exists before importing. I can import as long as a user does not exist however I am having trouble checking if users exist and only importing if they do not. Here is my code so far.
[Code]....
I am createing user dynamially with the below code; string MyPassword = Membership.GeneratePassword(8,0).ToString(); Membership.CreateUser(TextBox7.Text, MyPassword, TextBox8.Text); but before I start creating, I would like to check if the user name is used before or not.

I simply want to know how to manually check if the value a user has provided for the answer to their security question matches their current answer on record. I want to use the build in support of the ASP.Net membership and membershipuser objects.
I see that via the passwordrecovery control that the actual answer can be returned. However I am currently not using this control and it would take a good bit to integrate it as it does not meet our user's requirements.
In a worst case scenario, getting the actual answer (like the passwordrecovery control does) and manually checking it in our application would be acceptable.
A best case scenario is some sort of API where I can pass in the user name and the answer to their security question that was provided and simply get an indication of whether answer was correct or not.
I have a custom membership user class and custom MembershipProvider working against database. Due to security reasons the user passwords are stored in the database as hashed values. So my procedure
public override bool ValidateUser(string username, string password) is
{
//select hashed password from db
return (EncodePassword(password) == dbpassword)
}

I am using a create User Wizard for registering a user and have converted it to a a template to capture additional information. In the CreatedUserEvent handler in Code Behind I am getting the UserName of the new user and their unique GUID key. This is then added to a seperate data table with addditional info captured from the user. The textboxes within the create user Wizard have validation controls. If the user has missed an entry these fire and it shops the process of creating the user.
BUT If I then complete the textboxes and then click submit it says the USER NAME already Exists! This is not what I want as the User just needs to correct the errors in the form and they should be able to keep their iniital User Name choice. Do I need to change the Event handler and if so am I still able to capture the USerName and Key so that I can add the data to the other non membership table.
In the site I am building we have standard users and superusers. A superuser can delete another user from the system and this should result in that user being logged out (if he/she is currently logged in). We use the Membership provider. Or actually the superuser doesnīt delete the other user completely but instead sets his/her as inActive by following code:
[code]...
But, that should not matter... What I want to know is how to make the affected user being logged out. I donīt need a popup or anything to be shown to the other user that he/she is just logged out, it is enough to check if that user is logged in when he/she tries to move to another page on my site.
I'm trying to get the comments section for a user, to populate a text box which can be updated. I'm getting the "Object reference not set to an instance of an object" error. Why is this occurring?

View 1 RepliesWhen creating a foreign key to the membership user table, is it better to refer to the user_id column or is it ok to use the username column? I assume that the Membership spec enforces uniqueness in the username since there is a method Membership.GetUser(username) that returns one user. Using the id is a bit awkward in code because I have to end up casting all over the place like (int)user.ProviderUserKey. The username would give more information quickly when viewing raw data as well. Just wondering if someone knows a reason why I shouldn't use it as the foreign key.

View 1 Repliesif a user wants to clear their personal information from a page after clicking on a button that they be re-directed to the ASP Login page. This code needs to be developed using Java Script because I want the user to confirm with a confirmation box that they intended to clear their info. I have found resources on MS that pointed to referencing the "System Web Extension" within the Web Config file shown below, which enables Java Script to be able to reference the Authentication Service classes. I am also calling the function show_confirm in the button onclick event to process the message box response.
I also need to redirect a user back to the Login page within this same show_confirm() function without pointing directly to the URL, but instead to the folder where the page is locateded like in VB Server Redirect if possible.
The error message I receive when I run this code is: Microsoft JScript runtime error: 'sys' is undefined.

The passwords are hashed and when i try retrieveing his password i get the error that password retrieval is not available for hashed passwords.
Should i reset the password?
I realize that user names are unique, but is there another identifier associated with the username? If there is, how do I find out what it is for the user who is currently logged in?
