Managing master certificate
A master certificate can be either
			generated by the Service Expert as a
			self-signed certificate or you can import your own custom Certification Agency-signed
			(CA-signed) certificate. The certificate which is imported as a master certificate must
			be able to sign other certificates.
		Note: You must create
				a Master certificate, Web access certificate or both depending on which SSL/TLS
				encryption check box is selected in the Security
				section.
