If "local login" is enabled, all users are authorized against the LDAP backend. For "local user accounts" this will most likely fail.
Thanks for working on this. The issue is that I'm unable to login using a 'local' MediaWiki account once I've enabled the LDAPAuthorization extension on a wiki site. If I disable the LDAPAuthorization extension then "local" logins work fine.
We have multiple wiki sites and each site is restricted via a specific LDAP group so we need to use LDAPAuthorization to configure the required LDAP group. However, we also have a need to create and manage "local" users without LDAP authentication/authorization for guests/visitors.
Please let me know when we can expect a fix.
