### 1. FAQ

13.1.1. Does web-cyradm only support users like »test0001« ? I'd like to have a more descriptive username

web-cyradm does also support usernames like »user.name.example.com« if you configure it. Your need to change config.inc.php and change the value of DOMAIN_AS_PREFIX to 1. then you need to add »unixhierarchysep: yes« to your `/etc/imapd.conf`

13.1.2. Messages are bouncing. Postfix/pipe complains that "Mailbox does not exist". Whats wrong?

Check that the cyrus login on web-cyradm (config.inc.php) is correct. The username and password must exist in MySQL on table accountuser. Web-cyradm will not complain if the cyrus login info is incorrect.

13.1.3. web-cyradm complains about »Fatal error: Call to undefined function: bindtextdomain() in /www/web-cyradm-0.5.3/index.php on line 46«, whats wrong?

Web-cyradm needs gettext enabled PHP. Please compile PHP with the configure-option --with-gettext.

gettext is needed for NLS (Native Language Support) which means contributors can easily translate web-cyradm to there language. Fill in your Language in the file `/usr/local/apache/htdocs/web-cyradm/locale/templates/web-cyradm.pot` and send me the file, then your language will be supported in the next CVS snapshot

13.1.4. I got a error from Web-cyradm like this »Fatal error: Call to undefined function: query() in /usr/local/httpd/htdocs/web-cyradm/auth.inc.php on line 17«

Web-cyradm depends on PEAR for database abstraction. PEAR is included in recent PHP versions. Often PEAR is a separate package, check out the package base of your distribution. I strongly suggest to update to the most recent version of PHP anyway, because a lot of bugs have been fixed.

Another reason could be an authentication error with MySQL. Be sure the user »mail« has enough rights to access the database and tables.

13.1.5. Why MySQL and not LDAP?

Good question. LDAP is role-based and it would be indeed a better solution for such applications. Unfortunately LDAP is very hard to set up. You have to make proper schemes etc. MySQL is the way strait ahead, it is very easy to handle and versatile. There is a PAM module available for LDAP, feel free to use it.

13.1.6. Why Postfix and not Qmail?

Lots of people like to see such a setup with Qmail. The reason why is, Mysql-support is a hack and not in the included in the main source-tree. This could end up in a bad situation. Think if a security-hole is found in qmail and the patch does not work with the corrected version. Postfix is supporting MySQL natively. Another (personal) reason is that I find Postfix more sympatic (I don't know why)

13.1.7. I got a Error: "Temporary lookup failure"

Postfix cannot look up the alias table. Must common failure is that MySQL is not running, or there is a authentication Error. Check `/var/log/mail` and `/usr/local/mysql/var/<hostname>.err` to track the error.

13.1.8. For what platforms does this HOWTO work?

It is primarily for Linux. Until now I only tested it on Linux/IA32. Most probably it will also work on other architectures. FreeBSD is reported working fine. AIX has problems with at least PHP. Please report if you got it running on other platform, so I can update this section.
