creating user-mailboxes without cyradm

[Philipp Leusmann]

Hello,

is there a way to create INBOXes for users by IMAP-commands instead of using
cyradm? I want to control the creation of mailboxes from a java-servlet.
Another strange thing is, that I cannot use cyradm at all. I have set up
cyrus to use sasl-auxprop authentication against a mysql-db. logging in to
imap works fine using this authentication and the user listed as admin in
/etc/imapd.conf was even able to create his own inbox using the
CREATE-command in imap.
But when I try to login to cyradm with this user it always looks like this:

---snip---
sh#: cyradm --user testuser 127.0.0.1
Password:
cyradm: cannot authenticate to server with  as testuser
---snip---

Anyone knows what is missing between 'with' and 'as'?

Help would be great,
 Philipp
