Hello, We experience a few weeks of difficulties in accessing adminitrations pages XWiki spaces whether with users with administrative authorizations, as well as the user "superadmin" (not present in the database). Our context is: - XWiki 5.4.4 - Authentication via LDAP We suspect a change of data in database on one or more pages with the side effects unable to manage now the XWiki instance in its entirety. We would have an analytical view correction track at the database (Which table to control, what (s) line (s), what (s) data (s) ?). Thanking you in advance for items you can give us about it. Sincerely, Anthony H.
