Open source wiki's are easy to find, but an open source wiki with both LDAP and Confluence's level of ACL is scarce. Specifically most wikis and CMSs have ACL for whole wiki pages, but not ACL for certain parts of a wiki page or individual files.
Does an open source wiki with these features exist?
It's surprising to know that after all these years, Confluence still has no open source equal.
