Yes SOGo is able to do that, but you would need to use 2 SOGoUserSources. Which means you do not get one global address book, but 2 instead. > - If it can use 2 LDAP server then I don't have to join the server to > the local domain, am I right? Yes. > - Is it possible to use MAPI in this setup? No, because openchange only can talk to one SAMBA 4 server/cluster. > - If no MAPI is possible how can an Outlook access the calendar data? > Is it a preferred way to do this? (Sorry I never used Outlook > before.) There are currently 2 possibilities. 1) ActiveSync which only works with Outlook 2013 + 2016. You also have to synchronize emails over that, which is not the most efficient solution. 2) Outlook CalDAV Synchronizer https://sourceforge.net/projects/outlookcaldavsynchronizer/ This must be installed on every machine using Outlook and configured seperately. > - Is it possible in this setup to use SSO?

But you have to use that too for IMAP and SMTP, because SOGo authenticates with the user credentials given on authentication (credentials are not available with SAML2, only session tickets). For other clients that is not possible. > If this can be solved by Sogo then I'll tell the customer to buy a > support package. > > Thanks, > > > Árpád Kunszt > Kind regards, Christian Mack -- Christian Mack Universität Konstanz Kommunikations-, Informations-, Medienzentrum (KIM) Abteilung Basisdienste 78457 Konstanz +49 7531 88-4416
