[MediaWiki-l] Using two primary authentication providers?

I just installed LDAP Authentication and it worked fine after setting it with $wgAuthManagerAutoConfig:

$wgAuthManagerAutoConfig['primaryauth'] += [ LdapPrimaryAuthenticationProvider::class => [ 'class' => LdapPrimaryAuthenticationProvider::class, 'args' => [[ 'authoritative' => true, ]], 'sort' => 50, ], ];

I can enable either LdapPrimaryAuthenticationProvider or LocalPasswordPrimaryAuthenticationProvider, but not both. I can switch the authentication method by changing the value for the 'sort' key (LocalPasswordPrimaryAuthenticationProvider has 'sort' => 100), but I couldn't figure out how to allow both LDAP and local accounts.

I tried to set 'authoritative' => true, and I also tried it as false, but none of them seem to work.

Is there anything I'm missing?

Thanks.
