You need createUser action to create users on a DB
So give this action on the resource you need or choose a built in role which has this action
Check mongodb documentation for userAdmin role

second admin can access all roles without specified in the roles.

but second cannot change superadmin or user password.

4

Built in role are include changepassword and remove user.

I wanna create two admins.
One has all the permission like superadmin

second one only can view all db, createdb, removedb, createuser.
for changepassword and remove user i dont want second admin can has this two permission.

after i create new roles for the second admin. they can createdb removedb but cannot createuser

db.createRole(
{
role: “oo2”,
privileges: [
{ resource: { db: “admin”, collection: “” }, actions: [ “changeCustomData”, “dropDatabase”, “createUser”, “setAuthenticationRestriction”, “updateUser”, “viewUser”, “insert”, “find”, “resync”, “createSearchIndexes” ] }
],
roles:
}
)

db.createUser( { user: “testUser”,
pwd: “password”,
roles: [ { role: “oo2”, db: “admin” },
{ role: “readWriteAnyDatabase”, db: “admin” }
] } );
