Field		Description
Allow basic		Normally, if calendaring is enabled, the Polycom DMA
authentication to		system authenticates itself with the Exchange server
Exchange server		using NTLM authentication.
		If this option is selected, the Polycom DMA system still
		attempts to use NTLM first. But if that fails or isn’t
		enabled on the Exchange server, then the DMA system
		falls back to HTTP Basic authentication (user name and
		password).
		We recommend using NTLM authentication rather than
		enabling this option.
		In order for either NTLM or HTTP Basic authentication
		to work, they must be enabled on the Exchange server.
Skip certificate		Normally, when the Polycom DMA system connects to a
validation for server		server, it validates that server’s certificate.
connecting		This option configures the system to accept any
		certificate presented to it without validating it.
		We recommend using valid certificates for all servers
		that the system may need to contact rather than
		enabling this option. Depending on system
		configuration, this may include:
		MCUs
		Active Directory
		Exchange
		RealPresence Resource Manager or CMA system
		Other DMA systems
Skip certificate		Normally, during encrypted call signaling (SIP over
validation for encrypted		TLS), the Polycom DMA system requires the remote
signaling		party (endpoint or MCU) to present a valid certificate.
		This is known as mTLS or two-way TLS.
		This option configures the system to accept any
		certificate (or none).
		We recommend installing valid certificates on your
		endpoints and MCUs rather than enabling this option.
