the first instances has ldap configured on the domain ldap-domain.com
the second instances is for the deployment of mail and other corresponding services.
the second server is on maildomain.com
this is contrary to what should happen, considering the mail server is setup on the second domain and not the first. the first is only for authentication.
on other mail clients, they are handled correctly.
because the other server is an administrative and monitoring server, which also hosts ldap users.
while the other is a collaborative server with things like mail, nextcloud etc
As far as i can understand, this do not configure the necessity for two different domains, only two different hostnames.
So maildomain.com should be the domain of both servers.
Webtop => Default groupware of the distro
sOGO => currently installable, but not default anymore.
Anyway, the way should be the configuration sogo, which as far as I can understand reads from SSSD ldap-domain instead of maildomain
its like the systems can not use a domain configured on ldap,
then have multiple other domains configured on the same ldap.
the emails will simply not work
av just seen even the mail for nextcloud app does not work
Not sure to understand, but SOGo uses the first configured domain name of the server, however for each user you can modify the real domain name they will use in the sogo user setting page
