I created a Unix file system repository on a portal running on the same Unix server. So, the file system is a mount point on my local host. I configured it to use the AclSecurityManager and the ca_rsrc_acl cache.
However, when I go into KM Content >> Toolbox >> Permissions, there is a grey box next to the folder and the message, "No security manager found for this item."
How do you configure security for the Unix file system repository?
