The following notes cover limitations pertaining to the Scanner process of Data Insight:
In case of Windows 2012 Severs used as Windows File Servers, the Scanner does fetch a group having permission based on a condition. For example, "all users who have xyz as manager have full access to the share/folder". However, the indexer discards it currently. The console does not display the group as having Dynamic ACL. The other permissions on the path are shown properly.
Resilient File System (ReFS) is supported only for scanning. Auditing is not supported since the drive cannot be attached to the filter driver.
Scanner does not support share names of more than 200 characters.
Scanner modifies the access time of directories while traversing the filesystem.
