Hi all,
I am facing the following problem with my sshd installation.

We are in an AD environment. AD holds the needed data for ssh(d) to 
work. I can log into cygwin using ssh. But if I have a key stored 
.ssh/authorized_keys for passwordless login, the groups my user is in 
differs from the one w/o an authorized keys. Unfortunately exactly the 
group(s) for accessing the shared filesystems is missing. We were 
investigating a lot and the only workaround we found is that the sshd 
service runs under the user we want to log in. This unfortunately 
disables any other user to log into the cygwin machine. When debugging 
ssh with -vvv, there is no visible difference between the login with 
authorized_keys or without (of course there is a difference wrt. the 
login method).

This is cygwin 3.2.0 and openssh openssh-8.8p1-1.

Any clues ?

Best regards

Dominik
