Cygwin/OpenSSH V.5.3: Key authentication does not work under Windows 2008...

- Subject: Cygwin/OpenSSH V.5.3: Key authentication does not work under Windows 2008...
Dear Cygwin experts,
we installed Cygwin/OpenSSH V.5.3
CYGWIN_NT-6.1-WOW64 d00atq49 1.7.1(0.218/5/3) 2009-12-07 11:48 i686 Cygwin
OpenSSH_5.3p1, OpenSSL 0.9.8l 5 Nov 2009
on a Windows 2008 64-bit system.
Unfortunetly the key authentication does not work. The connection
initiation interrupts on server side with the following errors: seteuid
<user-id>: Permission denied
debug1: userauth-request for user testuser01 service ssh-connection method
none
debug1: attempt 0 failures 0
debug3: Trying to reverse map address 10.2.240.11.
debug2: parse_server_config: config reprocess config len 229
debug2: input_userauth_request: setting up authctxt for testuser01
debug2: input_userauth_request: try method none
Failed none for testuser01 from 10.2.240.11 port 2467 ssh2
debug3: Wrote 80 bytes for a total of 1549
debug1: userauth-request for user testuser01 service ssh-connection method
publickey
debug1: attempt 1 failures 0
debug2: input_userauth_request: try method publickey
debug1: test whether pkalg/pkblob are acceptable
debug1: temporarily_use_uid: 1011/513 (e=18/544)
seteuid 1011: Permission denied
debug1: do_cleanup
The password authentication with the same user on the same server works
fine.
The OpenSSHd service is running under system account. The file
cyglsa64.dll is loaded from the registry key
"HKLM\SYSTEM\CurrentControlSet\Control\Lsa\Authentication Packages".
The public key file is owned by the user "testuser01", to which I want to
switch to, and is readable for group and all others.
The OpenSSHd service is running without Privilege Separation (we also
tried this in meantime, but fails, too). It's the same configuration as we
have used since years on our Windows Server 2003 systems (32-bit).
What can be the reason(s) for this behaviour?
Thanks for help in advance and
best regards
Carsten Porzler
