Joomla
Configuration for authPDO plugin to login to DokuWiki with existing Joomla username & password.
Scenario
The intention is to permit the users registered on Joomla site to make edits in the Wiki, using the same credentials. This does not give a 'single sign-on' experience, just enables a user to have the same username, password etc. on both Joomla and Dokuwiki installations.
Works on PHP 7 + MySQL + Joomla 3.9.
Wiki Configuration
Just in case, backup conf/local.php
In the AuthPDO section, configure the following:
| plugin>authpdo>debug | Checkbox - enable this for testing, otherwise disable |
| plugin>authpdo>dsn | mysql:host=localhost;dbname=<DB NAME>;charset=utf8mb4 |
| (← That is, if the charset in Joomla DB is utf8mb4; otherwise just utf8). | |
| plugin>authpdo>user | <DB-USERNAME> |
| plugin>authpdo>pass | <DB-PASSWORD> |
| plugin>authpdo>select-user | SELECT `username` AS user, `password` AS `hash`, `email` AS mail, `name`, `id` AS uid from `#__users` WHERE (`username`= :user AND `block`=0); |
| (1. Replace “#_” in the table name with actual prefix of that DB, e.g. it could be jos_users. 2. `block`=0 means do not authenticate blocked users, such as spammers). |
|
| plugin>authpdo>select-user-groups | SELECT `title` AS `group` FROM `d0_user_usergroup_map` AS m, `d0_usergroups` AS g WHERE m.`group_id` = g.`id` AND m.`user_id` = :uid; |
In the Authentication section:
| authtype | authpdo |
| passcrypt | bcrypt |
| superuser | <USERNAME OF THE SUPERUSER> |
| disableactions | register |
And if you like to replace default DokuWiki groups with group structure from Joomla:
| defaultgroup | Registered |
| superuser | @Super Users |
In ACL settings, assign to group @Registered the same rights as @user.
It's posible to add settings for typical Joomla groups “Author”, “Manager” etc., according to your particular needs.
