shared mailboxes with virtual domain setup

[Philippe Trolliet]

hi,
i´m using cyrus-imapd-2.2.12-6.fc4 on fedora core 4 with virtual domains.
virtual domain and user information is stored in a mysql database. the
authentication works with sasl configured with pam.
everything works fine. i can check mails over pop/imap and send mail. the
usernames are of the following format user at domain.com.
i want to create shared mailboxes with user-specific access rights. in the
cyrus documentation i´ve seen that i have to use the command cyradm for it.
$ cyradm --user <admin-user> localhost

i created a mailbox with the command:
localhost> cm shared.department1

then i´ve set the access rights:
localhost> sam shared.department1 user at domain.de lrs

i get the error message:
setaclmailbox: <user at domain.de>: lrs: Invalid identifier

i created the domains and accounts with a cvs version of web-cyradm.
listmailbox produces the following output (changed usernames and domains):
user/user1 at domain1.de (\HasNoChildren)
user/user1 at domain2.de (\HasChildren)
user/user1/test at domain2.de (\HasNoChildren)
user/user1 at domain3.de (\HasNoChildren)

why doesn´t the above command work?
is it possible to define a shared mailbox for users that already have a
mailbox?
how can i setup an imap connection in outlook or thunderbird (the user could
already have an imap connection to his own mailbox)?
is it possible to define a shared folder for a user-account? how can other
users access this folder if they already have an imap connection?

regards
philippe
