Hi,

We are using LogOnuser API to authenticate users in windows workgroup 
environment and AD/Domain environment. The API works fine in AD/Domain 
environment, but we found an issue in Workgroup environment.

Following is the API we are using:

auth = LogonUser(userName, Server_Domain_Name, decryptedPassWord,
                            LOGON32_LOGON_INTERACTIVE, 
LOGON32_PROVIDER_DEFAULT,
                                ref pExistingTokenHandle);

No matter what the Server_Domain_Name argument is passed to the API, for a 
valid userName/Password on the Log on Computer/Server, the user is getting 
authenticated ( I believe the API is internally using the local Computer 
Name, if the supplied argument is invalid).

Just I was wondering whether this is an issue with this API (for invalid 
computer/Server name, the API is defaulting it to Local computer) or is there 
any setting in my computer is causing this behavior.

Thanks
Vizai
