Using an H.350 directory with other authentication mechanisms
Local database authentication in combination with H.350 directory authentication
You can configure the VCS to use both the local database and an H.350 directory.
If an H.350 directory is configured, the VCS will always attempt to verify any Digest credentials presented to
it by first checking against the local database before checking against the H.350 directory.
H.350 directory service authentication in combination with Active Directory (direct) authentication
If Active Directory (direct) authentication has been configured and NTLM protocol challenges is set to
Auto, then NTLM authentication challenges are offered to those devices that support NTLM. Devices that do
not support NTLM will continue to receive a standard Digest challenge.
