App Volumes uses NTLM to identify and authenticate computer and user windows sessions. The NTLM mechanism allows Windows to provide App Volumes Manager information about the computer and user. App Volumes Manager uses this information for identification purpose.
App Volumes Manager uses LDAPS and channel binding. For information about LDAP channel binding, see the Microsoft documentation.
Channel binding tokens make LDAP authentication over SSL or TLS more secure against man-in-the-middle attacks.
