Not able to create mailbox with fully qualified userid

[plcyrus]

Hi,

I have recently finished installing an exim4/cyrus setup. All went fine
in the end, so I decided to venture further and try and have the sever
serve multiple mail domains. I have configured the MTA for this task,
and generally researched the matter rather diligently, but I stop at
this weird obstacle: 

When I, logged into cyradm as user cyrus who in /etc/imapd_conf is
defined as admin, try to create a user in this manner:

cm user.<username>@dom.ain

 I get

createmailbox: Permission denied 

I can create mailboxes for user.<username>

for the default domain, but am not allowed to create for other domains.

I thought that the user defined "admin" in imapd_conf was omnipotent in
cyradmin, exept for the hoop concerning deleting mailboxes. What am I
missing? Why am I not allowed to do this? Am I being obscenely stupid?
It feels that way.

My Imapd_conf:



# Debian Cyrus imapd.conf
# See imapd.conf(5) for more information and more options
virtdomains: 1
defaultdomain: my-mailserver.net


# Configuration directory
configdirectory: /var/lib/cyrus

# Which partition to use for default mailboxes
defaultpartition: default
partition-default: /var/spool/cyrus/mail

# News setup
partition-news: /var/spool/cyrus/news

# Alternate namespace
# If enabled, activate the alternate namespace as documented in
# /usr/share/doc/cyrus21-doc/html/altnamespace.html, where an user's
# subfolders are in the same level as the INBOX
# See also userprefix and sharedprefix on imapd.conf(5)
altnamespace: no

# UNIX Hierarchy Convention
# Set to yes, and cyrus will accept dots in names, and use the forward
# slash "/" to delimit levels of the hierarchy. This is done by converting
# internally all dots to "^", and all "/" to dots. So the "rabbit.holes"
# mailbox of user "helmer.fudd" is stored in "user.elmer^fud.rabbit^holes"
unixhierarchysep: no

# Munging illegal characters in headers
# Headers of RFC2882 messages must not have characters with the 8th bit
# set. However, too many badly-written MUAs generate this, including most
# spamware.  Disable this if you want Cyrus to leave the crappage untouched
# and you don't care that IMAP SEARCH won't work right anymore.
#munge8bit: no

# Forcing recipient user to lowercase
# Cyrus 2.1 is case-sensitive.  If all your mail users are in lowercase,
it is
# probably a very good idea to set lmtp_downcase_rcpt to true.  The
default is
# to assume the user knows what he is doing, and not downcase anything.
lmtp_downcase_rcpt: yes

# Uncomment the following and add the space-separated users who
# have admin rights for all services.

# admins: entry above

# Space-separated list of users that have mupdate "admin" status, in
# addition to those in the admins: entry above. Note that mupdate slaves
and
# backends in a Murder cluster need to autenticate against the mupdate
