Is it authenticated domain user?

Asked by: NetwrkGuru

Hi,

I have a token (hAccessToken) belonged to a current user:

::OpenThreadToken(::GetCurrentThread(), TOKEN_QUERY, TRUE, &hAccessToken));

Is it possible to determine whether a user is authenticated in domain or not? How?

The easy way is: Compare the value of the "USERDOMAIN" env. variable to the local computer name. If they're identical, you have a local logon. The hard way: Use 'LsaQueryInformationPolicy()' as described in http://win32.mvps.org/lsa/lqip2.html

 

by: NetwrkGuruPosted on 2004-10-04 at 09:51:25ID: 12218972

I can't obtain "USERDOMAIN" because my code will work on the other machine using DCOM protocal. I have only security token.

 

by: jkrPosted on 2004-10-04 at 09:54:55ID: 12219020

Then you'll have to go the hard way. Get the Token's UserSID and use the code at http://win32.mvps.org/lsa/lsa_lqip2.cpp

 

by: Milind00Posted on 2004-10-05 at 22:45:39ID: 12234646

When ever you get an access token, it is always after autheticaion. The user is already authenticated in your case.  Why do you want to check this again?

 

by: NetwrkGuruPosted on 2004-10-05 at 23:20:16ID: 12234944

User can be authenticated within workgroup or within domain. I want know exactly that user is authenticated within domain.

Code at http://win32.mvps.org/lsa/lsa_lqip2.cpp works only for workstations. The question is still open.

 

by: Milind00Posted on 2004-10-06 at 07:01:32ID: 12237625

http://win32.mvps.org/lsa/lsa_lqip2.cpp  this code only tells you that where the machine is. By this you will not know if the user is logged on to machine or domain. The user could be a domain user or machine local user. You can use GetTokenInformation by specifying  " TokenUser" and get the SID of the user. And from the SID you can seperate out RID. Remainig will be domain SID or machine SID. You can verify that.
