Hi, I am working on windows credential providers and i have problem in accessing the credential providers. Credential providers work well for windows logon ,switch user, restart, log off hibernate and shut down but does not work for lock and sleep. What is the problem? I want add available domains in system dynamically? how do i do that? i want to show only one tile for any user that is of domain or a localhost. Please help me. Surbhi Jain.

Hi, Could you please provide us with more information such as which Operation Systems are you working with? Thanks. Per my understanding, in previous versions of Windows, WINLOGON.EXE loaded the Graphical Identification and Authentication DLL (GINA) specified in the registry to display a logon UI prompting users for their credentials. Windows Vista/7 and Windows Server 2008(R2) do not use the GINA, instead there is a new Credential Provider architecture in place. WINLOGON.EXE launches LOGONUI.EXE to load the credential providers that are configured in the following registry key: HKLM\Software\Microsoft\WindowsNT\CurrentVersion\Authentication\Credential Providers. LogonUI can host multiple credential providers concurrently and managers the UI displayed to users. Credential Providers may also specify custom elements to display on the logon screen. Once the user credentials have been passed to WINLOGON.EXE by LOGONUI.EXE, the LOGONUI.EXE process exits Regards, DennyPlease remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.
