## OpenLDAP backend special

### Add `enabledService=lda`, required by Dovecot 2.x.

Note: If you're running dovecot-1.1.x, or 1.2.x, then please stay on that version, but it's still recommended to add this missing value for existing users. It won't impact current mail services.

Note: Dovecot-2.x is the default version on RHEL/CentOS/Scieitnfic Linux 6.x.

Dovecot-2.x requires `enabledService=enablelda` for receiving email for virtual mail users, so we should add it if users doesn't have it.

- Download python script used to adding missing values.

    # cd /root/
    # wget http://iredmail.googlecode.com/hg/extra/update/updateLDAPValues_072_to_073.py

- Open `updateLDAPValues_072_to_073.py`, config LDAP server related settings in file head. e.g.

    # Part of file: updateLDAPValues_072_to_073.py

    uri = 'ldap://127.0.0.1:389'
    basedn = 'o=domains,dc=iredmail,dc=org'
    bind_dn = 'cn=vmailadmin,dc=iredmail,dc=org'
    bind_pw = 'passwd'

You can find required LDAP credential in iRedAdmin config file or `iRedMail.tips` file under your iRedMail installation directory. Using either `cn=Manager,dc=xx,dc=xx` or `cn=vmailadmin,dc=xx,dc=xx` as bind dn is ok.

- Execute this script, it will add missing values for mail accounts:

    # python updateLDAPValues_072_to_073.py

## MySQL backend special

- Add new column: `mailbox.enablelda`, required by Dovecot 2.x, used to replace `mailbox.enabledeliver`.

    $ mysql -uroot -p
    mysql> USE vmail;
    mysql> ALTER TABLE mailbox ADD COLUMN enablelda TINYINT(1) NOT NULL DEFAULT 1;
    mysql> ALTER TABLE mailbox ADD INDEX enablelda (enablelda);
