Allow Collaborators to Invite Other Users - If this setting is disabled, the checkbox Allow collaborators to invite other collaborators will not appear when inviting users to folders. This will prevent invited users from inviting other users.
Single File Sharing Expiration
Enable Single File Sharing - When enabled, allows the sharing of single file links and lets you control how users access them and the duration for which they are accessible.
Folder Sharing
Require that Shared Folders Expire - When enabled, all shared folders will be required to have an expiration date.
Whitelist
If the whitelist is enabled, only users in the configured LDAP groups or with the email domains (like example.com) specified in the list can login. Wildcards can be used for domains (e.g. *.example.com). LDAP groups must be specified by their distinguished names, such as CN=mygroup,CN=Users,DC=mycompany,DC=com.
Blacklist
Users in LDAP groups or with the email domains (like example.com) specified in the blacklist will not be permitted to log into the system, even if they are in the whitelist. Wildcards can be used for domains (e.g. *.example.com). LDAP groups must be specified by their distinguished names, such as CN=mygroup,CN=Users,DC=mycompany,DC=com.
Note: Wildcard entries can only contain one star and it should be always at the beginning of the string and followed by a period, (e.g. *.example.com, *.com).
