Just tried a new install, I do not reproduce your error.
Could you please provide more info about your configuration, and what you did with your wordpress after the installation.
Well, nothing changes, despite the following operations:
I saved all the tables except the user table.
I made a backup of the wordpress folder.
deletion of the application.
installation of the application.
deletion of tables in the newly installed database.
restoration of my tables
plugins restoration, backed up data
connection on the site, update of the database
attempt to connect to the administration interface and there I still get the same message.
Simple LDAP Login : Simple LDAP Login could not authenticate your credentials. The security settings do not permit trying the WordPress user database as a fallback.
I succeeded by overriding the application and reinstalling it.
I checked that in the newly installed version I connect correctly => youpi it works.
so I copied from my archive the images I had for my site.
I then injected the table data into the references of the articles already created.
I then installed the plugins and started to reset the values I need by sql request.
I haven’t finished going through the changes, but what a damn incomprehensible bug.
