1. A teleconference system comprising a security server and a conference management server, the teleconference system being configured to perform a teleconference through a network,
the security server comprising: a first communicator configured to connect to the network; a first hardware processor; and a first memory storing instructions, the instructions, when executed by the first hardware processor, causing the first hardware processor to perform:
a determining operation of determining whether address information of a terminal apparatus operated by a conference participant is included in a particular range;a first transmitting operation of:
when the address information of the terminal apparatus is included in the particular range, transmitting first authentication information corresponding to the conference participant from the first communicator to an authentication server, the first authentication information being acquired from the terminal apparatus through the first communicator, the authentication server being configured to authenticate usage of a function through a network corresponding to the particular range; andwhen the address information of the terminal apparatus is outside the particular range, transmitting second authentication information corresponding to the conference participant from the first communicator to the conference management server, the second authentication information being acquired from the terminal apparatus through the first communicator, the conference management server being configured to authenticate connection to a conference server configured to control the teleconference;a second transmitting operation of, when an authentication result satisfying an authentication condition is acquired through the first communicator from the authentication server in response to transmission of the first authentication information, transmitting third authentication information from the first communicator to the conference management server, the third authentication information corresponding to the first authentication information and being generated by the security server; anda third transmitting operation of:
transmitting a second authentication result from the first communicator to the terminal apparatus that is a transmission source of the second authentication information, the second authentication result being acquired from the conference management server through the first communicator in response to transmission of the second authentication information; andtransmitting a first authentication result from the first communicator to the terminal apparatus that is a transmission source of the first authentication information, the first authentication result being acquired from the conference management server through the first communicator in response to transmission of the third authentication information, the conference management server comprising: a second communicator configured to connect to the network; a second hardware processor; and a second memory storing instructions, the instructions, when executed by the second hardware processor, causing the second hardware processor to perform:
an authenticating operation of:
when the second authentication information is acquired from the security server through the second communicator, authenticating connection to the conference server based on authentication information stored in a management portion of the conference management server and on the second authentication information; andwhen the third authentication information is acquired from the security server through the second communicator, authenticating connection to the conference server based on authentication information stored in the management portion and on the third authentication information; anda fifth transmitting operation of transmitting an authentication result by the authenticating operation from the second communicator to the security server. |
