Thread:Project:Support desk/Installation. Database and user already created in cpanel. Installation cannot complete because mediawiki wants to create or grant database user privileges, and so fails./reply (8)

This appears to be broken in the 1.17.0 release if you use a different database access user than your installation database user, if that installation user doesn't have the rights to grant rights to the database user. This would be the case if, for instance, you don't use "root" in MySQL as the installation user, instead using a specific database maintenance account without GRANT OPTION or any other user management privileges. Such an account might be the wiki maintenance/admin user, which would have full DDL rights to the wiki schema but no user management rights for the server as a whole.

Perhaps a checkbox is needed to indicate that the specified "database account for web access" already has the necessary grants and that no changes should be made to it.
