Roundcube uses a SQL database (SQLite/MySQL/PostgreSQL) to store user's preference, personal contacts, etc. but it doesn't store mail user accounts.

My question should have stated; Can I use Roundcube with my existing LDAP server?  I know Roundcube needs MySql, so wasn't sure if that was a conflict. Since user authentication is implemented via dovecot, then it shouldn't be a problem.

Thanks.

1. Be careful: iRedMail uses its own ldap schema.

iRedMail has its own ldap schema file: http://iredmail.googlecode.com/hg/iRedM … ail.schema

You can only restrict services list below with this schema:

* Change LDAP server address, port number.
* Change LDAP filter.

Roundcube webmail is a web-based IMAP client, when you login webmail, user authentication is implemented by IMAP server (dovecot), not roundcube itself.

And i don't understand what you mean 'support a LDAP backend'...

1. Be careful: iRedMail uses its own ldap schema.

2. Besides postfix and dovecot, what other settings will need to be changed?

3. Does Roundcube webmail support an LDAP backend?

Thanks.

Setup a iRedMail box in a new server, and then change dovecot/postfix/etc settings to use your ldap server.
