Information processing apparatus, information processing system, and non-transitory computer readable medium

1. An information processing apparatus comprising:

a processor programmed to function as:

an acquisition unit that acquires first group information concerning a user from authentication result information including an authentication result transmitted from an external apparatus in a case where the user is authenticated by the external apparatus; and

a permission unit that permits the user to use a service provided by the information processing apparatus within a range of authority set for second group information concerning the user in a case where the acquired first group information is associated with the second group information;

a first memory in which the first group information and the second group information are stored in association with each other; and

a second memory in which the second group information and second user information for specifying the user are stored in association with each other,

the acquisition unit acquires first user information in addition to the first group information from the authentication result information, wherein:

in a case where predetermined information is common to the first user information acquired by the acquisition unit and the second user information stored in the second memory, the permission unit permits the user to use the service within the range set for the second group information,

in a case where the predetermined information is not common, the permission unit causes at least the predetermined information of the first user information to be stored in the second memory in association with the second group information and permits the user to use the service within the range set for the second group information, and

the predetermined information includes at least one of a name of the user and address information of a terminal apparatus used by the user.

2. The information processing apparatus according to claim 1 , wherein the processor is further programmed to function as updating unit that updates the second group information stored in the second memory to the second group information stored in the first memory in a case where the predetermined information is common to the first user information and the second user information stored in the second memory and where there is a difference between the second group information stored in the first memory and the second group information included in the second user information stored in the second memory.

3. The information processing apparatus according to claim 1 , wherein

the first user information acquired by the acquisition unit does not include all pieces of authentication information necessary for authentication performed by the external apparatus.

4. The information processing apparatus according to claim 1 , wherein

the predetermined information includes the name of the user.

5. The information processing apparatus according to claim 1 , wherein

the predetermined information includes the address information of the terminal apparatus used by the user.

6. The information processing apparatus according to claim 1 , wherein the processor is further programmed to function as presenting unit that presents, to the user, a screen including an entry field for entry of authentication information for authentication of the user by the information processing apparatus and a connection initiator for connection with the external apparatus.

7. The information processing apparatus according to claim 6 , wherein

the presenting unit presents, to the user, a screen for entry of authentication information for authentication of the user by the external apparatus after connection to the external apparatus and transmits the authentication information entered on the screen to the external apparatus so that the external apparatus performs an authentication process.

8. The information processing apparatus according to claim 1 , wherein

the permission unit permits the user to use the service without entry of information for permission in a case where the user is authenticated by the external apparatus.

9. A non-transitory computer readable medium storing a program causing a computer to execute a process comprising:

acquiring first group information concerning a user from authentication result information including an authentication result transmitted from an external apparatus in a case where the user is authenticated by the external apparatus;

permitting the user to use a service provided by an information processing apparatus within a range of authority set for second group information concerning the user in a case where the acquired first group information is associated with the second group information;

storing, in a first memory, the first group information and the second group information in association with each other;

storing, in a second memory, the second group information and second user information for specifying the user in association with each other;

acquiring first user information in addition to the first group information from the authentication result information;

in a case where predetermined information is common to the acquired first user information and the second user information stored in the second memory, permitting the user to use the service within the range set for the second group information,

in a case where the predetermined information is not common, causing at least the predetermined information of the first user information to be stored in the second memory in association with the second group information and permitting the user to use the service within the range set for the second group information,

wherein the predetermined information includes at least one of a name of the user and address information of a terminal apparatus used by the user.
