OpenSSH: differences for public key and password authentication

[Jasper Moeller <mail at jasper-moeller dot de>]

Hi folks,

I'm sure I had found some references to this before, but I'm completely 
unable to dig them out again, so please bear with me.

We are using cygwin+openssh for remote logins from linux onto an WinXP 
machine, which we use for automated build processes. We set up public 
key authentication successfully, however, there seem to be some 
differences between publickey authentication and password authentication 
- mainly, when using the public key, several permissions are 
wrong/missing/whatsoever. On problem is when trying to access network 
shares (we use AFS, just to complicate matters further...), the other 
manifests itself when trying to run several .NET applications (NDoc and 
especially signtool.exe). We can work around most ones, except for the 
signtool issue :-(

I'd really hate going back to password logins since this basically 
prevents fully automated builds, so is there any way around it? Probably 
some server misconfiguration which I can't find out?

SSH server config excerpt:

- Uses privilege separation
- service starts as SYSTEM account
- CYGINW=ntsec
- Rest as suggested by ssh-host-config

Thanks in advance

JM
