Hi everyone.
I'm trying to configure PostfixAdmin on two servers wich have replicated databases and some partitions (including mailboxes). I can install and use PostfixAdmin on my first server.
When I try to access PostfixAdmin on the second server, my credentials don't work. I need to re-run setup.php but when I do this, the first server stops working. It looks like setup works only to one host.
Can anybody help me?
It might help if you clarify what you are doing/trying to achieve. If this is just "two mail handlers sharing everything to split the load" then I have a similar setup. What I've done is make a master backend (holds the database and runs Policy Daemon), and several mail handlers. Each mail handler has a replicated database (I found problems all sharing one, but I haven't yet thought of a way to test again without causing customer disruption) and mounts a common mailbox directory via NFS.
PFA runs on one of the frontends (the main one that holds the mail store and runs webmail), with credentials pointed at the backend database. I only ever update the backend database, and replication pushes the changes down to the frontend copies.
