Question

I am using custom credential provider and I have to validate password on user logon with my custom validation condition if the password failed my condition I have to open the User must change password prompt by without enable UMCP flag in AD. There is any way to do this ?

Hello,

If you want to open the "User Must Change Password" (UMCP) prompt during user logon using a custom credential provider in C++, you can achieve this by implementing your own logic for password validation and handling the UMCP scenario. However, keep in mind that this approach might not enforce the "User must change password at next logon" flag in Active Directory directly, as you mentioned not wanting to enable the UMCP flag in AD.

Here's a high-level overview of how you can handle this situation in your custom credential provider:

Custom Validation Logic: Implement your custom validation logic to check the user's password against your specified conditions. This can be done in your custom credential provider code.

Handle Failed Validation: If the password fails to meet your custom validation conditions, you can take appropriate actions. One option is to display a message to the user indicating that the password does not meet the required criteria and that they must change their password. You can also log this information for auditing purposes.

Open UMCP Prompt: To prompt the user to change their password, you can create a custom dialog or UI element that looks similar to the UMCP prompt. This dialog should inform the user about the password requirements and provide an option to change the password immediately.

Password Change: When the user decides to change their password, you can handle the password change process within your custom credential provider. The details of this process will depend on your specific implementation and the underlying system (e.g., Active Directory, local accounts).

Update Password: After the user successfully changes their password through your custom UI, you will need to update the password in the appropriate backend system (e.g., Active Directory) using appropriate APIs or mechanisms.

Remember that this approach is specific to your custom credential provider and does not directly interact with the "User must change password at next logon" flag in Active Directory. If you need to enforce that flag in AD, you may need to look into other mechanisms or work with your organization's IT administrators to enable that setting.

Additionally, it's important to consider the security implications of custom password handling. Passwords are sensitive information, and you should follow best practices to protect them properly during the validation and update process. Always keep in mind security and privacy requirements when implementing custom authentication mechanisms.
