Manual:AdminSettings.php

Details
The requirement for   (along with supporting file  ) was rudimentarily removed in MediaWiki 1.16.

Prior to MediaWiki 1.16,   was used to store database authentication credentials for man>Special:MyLanguage/Manual:Maintenance scripts|maintenance scripts and to control the availability of  .

It has finally been removed completely in MediaWiki 1.23.

Upgrading
If upgrading from a pre-1.16 version of MediaWiki to version 1.16 or later, the variables set in   file can be safely removed.

Prior to 1.16 [ edit ]
Manually create  in the root directory of the MediaWiki installation.

Typically, this is done by renaming   to   and then editing <tvar|AdminSettings> </> appropriately.

<tvar|AdminSettings> </> should set three variables:
 * - the name of a database account that has sufficient privileges to run the database man>Special:MyLanguage/Manual:Maintenance scripts</>|maintenance scripts. For MySQL databases, this account should have "superuser" privileges.  For PostgreSQL databases, this account should be the same account used for <tvar|DBuser></>.
 * - the password for the <tvar|DBadminuser> </> account.
 * - controls the availability of <tvar|profileinfo> </>.

Security
<tvar|AdminSettings></> contains sensitive information (account names and passwords) that can help an attacker compromise your database management system.

This is necessary to ensure that the owner for new tables is set correctly.
