Important: Do not update authLdap plugin to 2.5.4
This applies to both WP Managed and WP Developer apps.
Do not update authLdap plugin from inside WordPress to 2.5.4. There is a regression which breaks user roles. If you login as non-admin, that user has no user role attached.
https://github.com/heiglandreas/authLdap/pull/233 is the upstream pull request.
