Win7, NovellClient 2 SP1 IR5

We want to use functionality similar to "PassiveModeNDSLogin" with
XP-Client. TID 7004709 describes to set these options:
"Novell Logon" = OFF
"Login With Non-Novell Credential Provider" = ON

"In principle" it works, but no environment variables (DOS SET ...) are
set and search drives letters (Z: ...) are not appended to PATH in
Can anybody confirm this? Bug?

(BTW: BOTH options = OFF and calling loginw32.exe manually works,
environment variables are set...)
