 |
|
Hi,
I'm working on a DCOM server application that is accessed
by clients from remote machines. For this to work I had to
create a "mirror" user account on the machine the server runs
on for every client.
Since not every client should be able to access the same
information I want to check which client/user is currently
asking for a specific information.
Is there a way to find out which user account connected to
my server and called some function from within the function called?
thanks for any idea,

I was just looking for that exact same thing last week. I wanted my
COM out-of-process server to grab the Windows username of the calling
client inside one of my COM methods. I did not find anything definate
in that area. I did run across CoImpersonateClient(), hoping I could
impersonate the calling client and then use GetUserName(), but I do
not think it would work for me because the docs say
CoImpersonateClient() doesn't work for RPC_C_AUTHN_LEVEL_NONE
authentication, which I do use.

thanks Remy for your reply.
I will try what you suggested. Other things I found were
CoImpersonateClient
OpenThreadToken
GetTokenInformation
LookupAccountSid
or
CoQueryClientBlanket
but could get none of them consistently work yet.

I use CoQueryClientBlanket to identify calling client in my DCOM
servers
