Creating a super-admin without super-admin rights

In Mariadb :

show databases;  
use glpi;  
show tables;

Here is where you want to look. Your glpi_users table’s where your users_id is, mine happened to be 42; 60 was the next number available, 42 was my id number, and 4 is super-admin rights.

insert into glpi_profiles_users
(id,users_id,profiles_id,entities_id,is_recursive,is_dynamic) values(60,42,4,0,0,1);

To double check it worked run :

select * from glpi_profiles_users;
