We have Configured Confluence with LDAP authentication, It is working with OU level Access but not with Group level Access from Microsoft Active Directory
In Brief: If user is added to OU/Directory he is able to login into Confluence, But we are using the same OU for Jira and BitBucket and we have different users for Confluence and Jira, We have to restrict user to Group level (either Conflunce/Jira)
