There's a sm_overrides table that allows you to override commands when you run the sourcemod command in server console: sm_create_adm_tables
Also sm_admin_group(what ever it's name is I don't got access to my database to check), you define which admins are in which group:
Eg for me
Group 1 is owner
I'm index 1 as an admin
in the table sm_admin_group(index, admin index, group index) I put: 1 1 1
To sourcemod this is: the entry in table is read first because it's index 1, it locates admin index 1 which is associated with my entry in sm_admins table, it then finds group index 1 which is the Owner group which has all the flags defined for it, sourcemod assigns me to Owner group and grants me it's rights(which is every flag defined by sourcemod)
