Re: Set mail crypt private password with OAUTH?

Was the field present in auth debug logs, it should be shown in the "master out" log line and also it should be visible on mail_debug=yes logs as plugin/mail_crypt_private_key_password.

Aki, thanks for your hint. Unfortunatelly I can't get this work. Here is my configuration.

auth_mechanisms = $auth_mechanisms oauthbearer xoauth2 passdb { driver = oauth2 mechanisms = xoauth2 oauthbearer args = /etc/dovecot/dovecot-oauth2.conf.ext } passdb { driver = sql skip = unauthenticated args = /etc/dovecot/dovecot-sql-encryption.conf.ext } passdb { skip = authenticated driver = sql args = /etc/dovecot/dovecot-sql.conf.ext } userdb { driver = sql args = /etc/dovecot/dovecot-sql.conf.ext }

• In the dovecot-oauth2.conf.ext I have typical Google configuration.

• dovecot-sql-encryption.conf.ext contains only SQL query for password:

password_query =
SELECT
150 AS userdb_uid, 8 AS userdb_gid,
SHA2(CONCAT(username, random_key), 256) AS userdb_mail_crypt_private_password,
'Y' AS noauthenticate
FROM mailbox WHERE username = '%u'

• dovecot-sql.conf.ext contains normal password authentication queries:

password_query =
SELECT username AS user, password,
150 AS userdb_uid, 8 AS userdb_gid,
SHA2(CONCAT(username, random_key), 256) AS userdb_mail_crypt_private_password
FROM mailbox WHERE username = '%u' AND active = '1'

user_query =
SELECT
CONCAT('/var/vmail/', LCASE(maildir)) AS home,
CONCAT('maildir:/var/vmail/', LCASE(maildir)) AS mail,
150 AS uid, 8 AS gid, concat('dirsize:storage=', quota) AS quota,
SHA2(CONCAT(username, random_key), 256) AS userdb_mail_crypt_private_password
FROM mailbox WHERE username = '%u' AND active = '1'

iterate_query =
SELECT username AS user FROM mailbox

It seems now dovecot-sql-encryption.conf.ext is not invoked

We currently use Dovecot and mailbox encryption via the mail-crypt-plugin. With standard password authentication, we set the value of the individual password to encrypt the contents of the userdb_mail_crypt_private_password mailbox in the SQL query. Is it possible to set the userdb_mail_crypt_private_password value when authenticating via OAUTH2 ?

-- Best regards, Max Kostikov

You probably want to split your passdb drivers into two, one which does the authentication and second which populates the private password value. This way it should work correctly on both cases.

passdb { driver = sql skip = unauthenticated ... }

and ensure your return in this sql query 'Y' as noauthenticate'
