Adjustprivilegesfailsifdatabasenamecontainsunderscores

Using phpMyAdmin 4.5.3.1, MariaDB 10.1.9, PHP 7.0.1.

If database-specific privileges are assigned to a user account on a database that has underscores in its name, Adjust privileges fails when copying or renaming a database. However, if the original database name does not contain underscores, Adjust privileges does work when copying or renaming to a database with underscores in its name. Further changes are also possible because the privilege type is changed from "database-specific" to "wildcard".
- Create a database called my_test, and create a dedicated user account on my_test with all privileges except Grant.
- In the Operations tab of my_test, copy the database to a new database called "another", leaving Adjust privileges selected.
- Select the "another" database, and select the Privileges tab. The original user account is not listed.
- Edit the privileges for the original user account to grant the same privileges on "another".
- In the Operations tab of "another", copy the database to "something_else", leaving Adjust privileges selected.
- Select the "something_else" database's Privileges tab. The user account is listed, but the type is "wildcard". Copying something_else or renaming it now correctly adjust's the user account's privileges.
