how can I check (and change) the owner of a mailbox ?

[Chentao Credungtao]

Hi again,

Almost there...
I found out that replacing in each cyrus.header file the ACL line "john.doe" by "john.doe at example.net" did the trick ! Now "john.doe at example.net" is the mailbox owner, and not "john.doe" anymore.

Everything works fine, except that now my log file is cluttered with :
Header CRC mismatch for mailbox example.net!user.john.doe

My questions :
- is there a way (other than messing with cyrus.header) to modify a mailbox owner ?
- if not, is there a way to rebuild cyrus.index, so it can take into account the new cyrus.header's CRC ?

Hi,

How can I check who the mailbox owner is ? How can I change it ? I'd
like to change owner john.doe tojohn.doe at example.net


Here's why :

I'm currently testing the migration of a single-domain Cyrus IMAP server
to a multi-domain one. I'm doing the migration on the filesystem level,
copying files from the old to the new server.

It works fine, except for the mailbox owner, it seems to be the old one,
without the e-mail domain.


Here is what I did :

- 1/? First I created user/john.doe on domain example.net on the new
server,? using autocreate (so it created
/var/spool/cyrus/mail/domain/e/example.net/j/user/john.doe)

- 2/ The I checked this mailbox's ACLs :
$ cyradm --usercyrus at example.net  localhost
localhost> lam user/john.doe
user/john.doe:
  ?john.doe at example.net  lrswipkxtecdan

- 3/ Then I stopped cyrus

- 4/ Then I copied/var/spool/cyrus/mail/j/john.doe/*? from the old
(single domain) server to
/var/spool/cyrus/mail/domain/e/example.net/j/user/john.doe on the new
(multi-domain) server

- 5/ Then a little reconstruct : su -c "/usr/lib/cyrus/bin/reconstruct
-r -fuser/john.doe at example.net" cyrus -s /bin/bash

- 6/ Starting cyrus

- 7/ Checking ACLs :
$ cyradm --usercyrus at example.net  localhost
Password:
localhost> lam user/john.doe
user/john.doe:
  ? john.doe lrswipkxtecda

- 8/ OK, so now john.doe (and notjohn.doe at example.net  like before)
seems to be the owner of user/john.doe

- 9/ When I try to log in (with my webmail for example), it doesn't
work. From the logfiles :
May 14 21:40:04 sogod [1596]: [ERROR]
<0x0x5648006b5480[NGImap4Connection]> could not select URL:
imaps://john.doe%40example.net@mail/INBOX/: {RawResponse =
"{ResponseResult = {description = \"Mailbox does not exist\"; result =
no; tagId = 6; }; }"; reason = "Mailbox does not exist"; result = 0; }

- 10/ Back to cyradm, and granting full rights tojohn.doe at example.net  :
$ cyradm --usercyrus at example.net  localhost
Password:
localhost> sam user/john.doe*john.doe at example.net  lrswipkxtecdan

- 11/ OK, after that webmail works fine.

- 12/ Back to cyradm, where my ACLs now look like :
$ cyradm --usercyrus at example.net  localhost
Password:
localhost> lam user/john.doe
user/john.doe:
  ? john.doe lrswipkxtecda
  ?john.doe at example.net  lrswipkxtecdan

So, I though I don't need the john.doe ACL anymore, and tried to remove it :

localhost> dam user/john.doe john.doe

But I still have "lkxca" ACLs, which are the owner's implicit ACLs :

localhost> lam user/john.doe
john.doe at example.net  lrswipkxtecdan
john.doe lkxca

So I guess after the migration the owner of the mailbox is john.doe, and
notjohn.doe at example.net  like before the migration. How can I change
this ? How can I get rid of john.doe's ACLs ?



Thanks,

Chen
