Hi there,

I'm trying to set up shared mailboxes such that any access to the shared namespace like INBOX/shared/<sub-email-address> will take <current-user> and use imapc to log in with <sub-email-address>*<current-user> (ie the current user is the master account for imapc). I've set up like https://wiki2.dovecot.org/SharedMailboxes/ClusterSetup on centos8 latest dovecot build (a late 2.2 series version I believe.

However I'm running in to a couple of issues:

1. setting imapc_master_user = %u has %u as <sub-email-address> rather than <current-user>. I can't find any sort of variable substitution that will allow me to access the details of <current-user>. From looking at the logs it seems to do a userdb lookup for<sub-email-address> to check it exists but then the substitutions appear to be using these rather than the current user's details

2. In a similar vein, I believe imapc_password = %w (ie trying to just get current user logging in with the password that was specified when they initially logged in, but as a master user) is also not substituting correctly and is just a blank string

Is there any way around this so I don't have to worry about trying to do sharing based on the filesystem and the same process but rather just allow the main user to log in to any other account (in this case domain owner logging in to any accounts under their domain) ?

Thanks

Mark
