Converting mbox to cyrus maildir w/ seen state preservation

[Miham KEREKES]

Hi,

I'm about to migrate user mailboxes from unix mbox mailbox format 
to cyrus maildir. Unfortunately, users have lots of separate 
mailfolders in mbox format, which i should convert, too.

I dig into the archive, and found the mailutil utility for doing this:
mailutil append /path/to/mbox {new.cyrus.server/user=mbox_cyrus_user/authuser=proxy_user/norsh}INBOX
and I figured out, that it is capable to creating mailboxes, too.

I've migrated the users Inbox already successfully, but with the
difference: that time I knew the users password (I created them with a
script before), so I had no need to use the /authuser=XXX option. 
Since then they've changed their password, so I don't know them. 
(Yes, I forgot about their ~/mail mailboxes :-( )
However, this time I need to use the /authuser=XXX, if I'm not mistaken. 

When I try this:
mailutil create {cyrus.server.name.or.ip/user=targetuser/authuser=cyrus_admin_user/norsh}INBOX.subfolder
I got the following errormessage:

Can't do /authuser with this server
Can't do /authuser with this server

I already strace'd and ltrace'd the process in order to know what is the
problem, but all I got to know, that mailutil parsing the output of the 
CAPABILITY command, and decides whether the server is capable of
authuser.

I don't have much time for this conversion, so I had no time to look
into the source, yet.

I have the following capabilities:
* CAPABILITY IMAP4 IMAP4rev1 ACL QUOTA LITERAL+ MAILBOX-REFERRALS
NAMESPACE UIDPLUS ID NO_ATOMIC_RENAME UNSELECT CHILDREN MULTIAPPEND
SORT THREAD=ORDEREDSUBJECT THREAD=REFERENCES IDLE AUTH=NTLM
AUTH=DIGEST-MD5 AUTH=CRAM-MD5 LISTEXT LIST-SUBSCRIBED ANNOTATEMORE

Can anyone give me a good point? I mean, which cap missing, how can I
enable, etc.

Thanks in advance,
