Starting with version 2020.0, mapping of administrators through Administrators.txt and AdministratorGroups.txt is no longer supported. The property access.administrator.groups should be used instead.
If the customer’s authentication method relied to the use of the Administrators.txt or AdministratorGroups.txt file, they can still do so by additionally using the tomcat-users.xml to replicate the usage of these administrator text files.
For example, in the tomcat-users.xml, they can assign groups from the administrator text files to specific users like this:
<user username="admin" password="admin" roles="role1,otherRole"/>
<user username="admin2" password="admin2" roles="role2"/>
Then in the Panopticon.propertiesfile, use the access.administrator.groups property to map the admins (i.e., admin and admin2) to the administrator groups by adding their roles:access.administrator.groups=role1,role2
