This is sort of a repost of a previous question to this mailing list.
I am running into

Fatal Error C1902: Program database manager mismatch; please check
your installation.

When attempting to use the visual studio compiler from within cygwin
when logged in via ssh.  I found the following in the archives:

Indeed this is what I observe, with one wrinkle (below)

I see that using password authentication does make the problem go away
for accounts local to the machine.  But if I ssh into this machine
using a domain account and use password authentication, whoami still
tells me that I'm the sshd_server.  (I built /etc/passwd using
'mkpasswd -c -l -d'; when on the console whoami says 'DOMAIN\username'
as expected)  Any ideas why this is?

Anyway, I was wondering if there is an actual fix out there or any
sort of workaround.  I'd really like to be able to use public key
authentication.  I thought I'd ask the list since I haven't seen any
traffic on this topic since July.  (Or, at least my search for "C1902"
only returned hits in July - please accept my apologies if I missed
something.)  Right now it looks like the only thing I can do is remove
this machine from the domain, add some local accounts, and use
password auth. :-(

Thanks in advance for your help,
