Hi, I tried to reproduce your steps and found the same behavior. It seems password for user 'openchange' has expired. For me it was resolved by changing the password for 'openchange' user:
on SOGO appliance side run: /usr/local/samba/bin/samba-tool setpassword openchange and type a new password. It's must help. I hope )) -- [email protected] https://inverse.ca/sogo/lists
