mitigate this issue, configure Apache to enforce a request-body limit for the `/ipa/i18n_messages` endpoint. This can be achieved by adding `LimitRequestBody` directive within the Apache configuration for IPA. For example, to limit the request body to 1MB, add `LimitRequestBody 1048576` to the relevant `<Location \"/ipa/i18n_messages\">` block or a broader `/ipa/*` location. A restart of the Apache HTTP Server (`httpd`) service is required for the changes to take effect, which may temporarily impact FreeIPA service availability.
