No option here: These four DokuWikis are enterprise wikis and we definitely need AD authentication.
On openSUSE Tumbleweed php8-8.1.14-1.1.x86_64 is active with these plugins (installed): acl, addnewpage, advanced, authad, authldap, authpdo, authplain, config, cookielaw, edittable, extension, gdpr, info, logviewer, move, nspages, pdfjs, popularity, revert, safefnrecode, scrapbook, sqlite, struct, styling, upgrade, usermanager and I do not get any error messages.
Might it be a problem of the PHP version?
