HI. I have a server SLES11 SP2 with postfix and cyrus imap server installed and normally executing. All work ok, but I need administer cyrus with graphical tool, for example webmin module or Web-Cyradm. I installed webmin and cyrus module but I obtain the following error and I can't administer cyrus
Error: some Perl modules are missing:

Tree::Simple

I have webmin webmin-1.580-1 version for suse.

I tried web-cryadm but I can't to do login with the user configured. I'd prefer to use webmin.

Please your help

Thanks
