Yes, we do this but note my NB at bottom:

*    GET THE USER LOGIN NAME

TUSER_LOGIN_NAME = ALLTRIM( SUBSTR( SYS(0), AT( "#", SYS(0) ) + 1 )  )
   
*    CREATE AN OBJECT REFERENCE TO THE USER LOGIN ACCOUNT

TRY

    TOBJ_Windows_User = getobject( "WinNT://" + Getenv("USERDOMAIN") + "/" + m.TUSER_LOGIN_NAME + ",User" )

CATCH

    TOBJ_Windows_User = .F.

ENDTRY
 
*    GET THE USERS FULL NAME AND DESCRIPTION

IF VARTYPE( TOBJ_Windows_User ) = "O"

     TUSER_FULL_NAME    = TOBJ_Windows_User.FullName    
     TUSER_DESCRIPTION = TOBJ_Windows_User.Description

ELSE

     TUSER_FULL_NAME    = "?"    
     TUSER_DESCRIPTION = "?"

ENDIF

NB: The above is relatively slow (a couple of seconds) and so our code tests to see whether the login full name is empty in our file and only attempts the above if empty. In other words, we run this code only once for a user and then not again.
