I have been trying to use (in C++) the AzMan api to open the authorization
store (xml file) for doing access as follows

AzStorePtr->Initialize(0, storeURL, VT_NULL);

The above initalize method is called from a DCOM service (MyService.exe)
running in WinXP SP2 machine, joined to the Win2K3 domain.

In one of the test domain, the Initialize method works fine no matter the
MyService.exe runs under the Local System or Local Service account.

But, in another test domain, the Initialize method works fine if the
MySevice.exe is run under the Local Service account, but fails if run under
the Local System account. When it fails, it returns with an error 0x80070057.

Does anyone have seen this before. Any kind of advice is greatly appreciated.
Thanks.
