Read logged in user-works in Delphi7 but not in Delphi 2010

Question

Hi all
I have some code I wrote a while back in Delphi 7 - simple program to read a currently logged in user IDs, read available class definitions, read some user attributes - relatively simple stuff. I am now trying to move to Delphi 2010 and the very same code that works on Delphi 7 does NOT work on Delphi 2010. The code was updated to compile and run on Delphi 2010, so it executes with no errors.
I am using NWDSWhoAmI to get the currently logged in user name and NWDSRead to retrieve user attribute values. On Delphi 7, the code works, all API return "Success" and return correct values. In Delphi 2010, all APIs return "Success" but the code act as if I am not logged in - the username returned is "[Public]" and when I try reading attribute values I get $8884 - RESOLVE SVC FAILED (also may mean I am not authenticated to the NDS tree).
The environment is XP and Novell Client 4.91 on the workstation, NW6.5 on the server (one sever tree). The code runs under the currently logged in user with full admin rights in the tree and Novell Client configuration on both workstations is identical. Any ideas on how to resolve this would be greatly appreciated.
Thanks
Vlad

Vlad,
since both Delphi versions go through the same DLLs it must be a difference
in the code - possibly different variable implementation as 16/32 bit or
signed/unsigned vars
It is good practice to use the NWLibrary defined variable types instead of
native Delphi types.
I have successfully used the same sources in Delphi 4, 5, 6, and 2010
Try my old samples:
http://support.novell.com/techcenter...a20020203.html and my Delphi
version independent Delphi libraries
