Hi Gilles,
I have used your imapsync program many times over the past few months
and it has been a great help in our mail server migration, so first of
all: Thank you! :-)
However, with the latest task, I ran into a problem: I'm migrating mail
from a Kolab 2.0.4 server to a Kolab 2.1beta2 server (both use Cyrus as
imapd). The problem is: We're also changing domains at the same time,
i.e. any user "NAME@OLD.DOMAIN" on the old server becomes
"NAME@NEW.DOMAIN" on the new server. When transferring mail, this
doesn't have any bad influence, but it does lead to problems when trying
to sync ACLs as well. Right now, imapsync will take the ACLs, compare
the folder on the old and the new server and will then happily set the
ACL for "NAME@NEW.DOMAIN" on the new server to "none" (because it
doesn't exist on the old server) and then try to set the ACLs for
"NAME@OLD.DOMAIN" on the new server - which a) fails (it just removed
the access for NAME@NEW.DOMAIN - hence, the user cannot access his own
mailbox anymore) and b) is not desirable anyway (only "NAME@NEW.DOMAIN"
should have permissions).
So, basically, what I need is an option to tell imapsync that the domain
is changing and have it replace the domain in all user names that are
related to ACLs. Right now, I've solved this by crudely patching the
"acls_sync" subroutine:
sub acls_sync {
my($f_fold, $t_fold) = @_;
[...]
foreach my $user (sort(keys(%users))) {
my $acl = $f_hash->{$user} || "none";
if ($user eq $user2)
{
# the user we use to log in as on the target
# server gets "all" permissions always
$acl = "lrswipcda";
}
my $new_user = $user;
$new_user =~ s/OLD.DOMAIN/NEW.DOMAIN/g;
print "acl $user -> $new_user : [$acl]\n";
next if ($f_hash->{$user} && $t_hash->{$new_user} &&
$f_hash->{$user} eq $t_hash->{$new_user});
unless ($dry) {
print "setting acl $t_fold $new_user $acl\n";
$to->setacl($t_fold, $new_user, $acl)
or warn "Could not set acl: $@\n";
}
}
[...]
but this is really just a hack to suit my current needs. Maybe you could
consider adding something more refined than this hack in a future release? :-)
Best regards,
Thomas
