Hello Timo, In order to plan a migration, I want to setup an IMAP proxy (proxy_maybe) with a dovecot server (I'm running the old dovecot-2.1.15 but I could upgrade or use a proxy only dovecot-2.2.x server)/LDAP pass et userdb's.
I'm won't be in charge of the migration itself but I think the idea will be to migrate a chunk of users each night and then let the proxy send them to the new server. I wonder if, instead of altering my LDAP schema to be able to add the needed attributes (matching proxy/proxy_maybe, host, ...) I could use a second userdb (preferably in a file : passwd-file ?) only for those extra_fields (i.e. the second userdb would extend the LDAP one). As a matter of fact, I guess those who will migrate users will prefer writing to a file than to add some LDAP attribute in the user entry. In other words, can I get different extra_fields for the same user in different userdb's ? -- Thomas Hummel | Institut Pasteur <[email protected]> | Groupe Exploitation et Infrastructure
