Does Managed File Transfer support restricting AD groups from accessing Managed File Transfer?

Does Vault supports restricting AD groups from accessing Vault? Does Vault supports restricting users of being shared with?

Yes, AD groups, or users belonging to AD groups can be restricted of being shared with a file - and that is done by denying their access to Vault.

Denying access is done via the Vault Settings / Active Directory / Configure and then in STAGE 5:

Include the Security groups (of users) which require access to Vault.

Exclude the Security Group (of users) which should not be shared with.

Complete the setup.
