I think we'll just jump in with both feet, and upgrade them all to v1.2
at the same time. If, in worst case, we need to downgrade, do we need to
delete all indexes first, or will the errors resolve themselves ?

I just tested accessing the same mailbox over imap first against v1.2
then against v1.0.15, and didn't see any problems logged. But maybe that
was too light testing to reveal any problems..

What would I then have on the left hand side of the expression instead
of ldap attribute ? Hmm, I think I'll stick with the ldap attribute, to
force us to keep the ldap data correct in case we ever want to replace
some parts of dovecot with something that doesn't allow such templating.
