In order to disable LDAP completely for @limesurvey you need to install the @limesurvey app with its own user management.

Otherwise, when Allow all users on this Cloudron is selected, every app restart will configure and active the LDAP plugin again.

I understand that you already have a @limesurvey app installed.
To migrate your @limesurvey app to the Leave user management to the app version you need to follow some steps:

• create a backup of your current @limesurvey app
• download the backup configuration
• install a new @limesurvey app and chose Leave user management to the app
• when the new app is fully installed go into the backup Backups settings of the new @limesurvey app and press Import Backup and then click upload a Backup Config to upload your previous downloaded config
• press Import
• the app then restores from your backup
• confirm everything is working in order
• you are done

Die Frage, die sich nun daraus ergibt, lautet: Wird LimeSurvey bei einem zukünftigen Update auf Cloudron die Erweiterung LDAP automatisch wieder reaktivieren? In dem Fall würde ich den vollständigen Zugriff auf Daten und Umfragen verlieren.
