Hi,
I tried to install the new 0.9.0 and new Admin Pro panel on a separate server before updateing.
The install of iredmail went through totally, I did not see any error.

When installiung the Pro Admin panel, I noticed that the iredmail user and group was missing.

Before installing iredmail, I did set up some normal users, probably this interefered with the setup of iredmail. Is there a way to fix this or will I have to start over?
It seems iredmail tries to setup the same user- and group-ids on every server to support cluster environments. But I could not find a clue what Ids are needed. What are they?

Thanks, greetings

Jochen
