It would be most helpful if you could provide more detailed info on how to modify the following parameters ;
- $wgAuthJoomla_MySQL_Host
- $wgAuthJoomla_MySQL_Username
- $wgAuthJoomla_MySQL_Password
- $wgAuthJoomla_MySQL_Database
- $wgAuthJoomla_TablePrefix
- $wgAuthJoomla_Path
The first four are easy enough I think.
The fifth ($wgAuthJoomla_TablePrefix) is hard to identify.
The last, ($wgAuthJoomla_Path) does not exist at all within the code as far as I can tell.
Maybe adding some more comment lines to document where to make substitutions so beginners don't struggle.
