After xWiki upgrade (might not be related) from 15.10.12 to 17.10.2 some users report issue with access rights to sub-wikis.
The xWiki is integrated with OIDC and SSO enabled.
In the installation history report there is information about the “Required Rights Application“ deinstallation.
Is it required for the sub-wiki access rights functionality?
How can we check the xWiki Installation consistency?
