Using application level authentication for network login

A non-transitory computer readable medium comprising instructions which, when executed by one or more hardware processors, causes performance of operations comprising:

• subsequent to a first client device being authenticated by a first authentication server;
• receiving by a second authentication server from a system (a) a request to authenticate the first client device for network access and (b) a first client authentication information comprising a first indication that the first client device has already been authenticated, wherein the system has forwarded the first client authentication information to the second authentication server without determining that the first client device has already been authenticated,
• wherein the system comprises one or more network devices;
• determining, by the second authentication server, that the first client device is authenticated for network access based on the first client authentication information comprising the firs indication that the first client device has already been authenticated;
• and
• transmitting, by the second authentication server to the system, a second indication that the first client device is authenticated to access the network,
• wherein the system provides network access to the first client device based on the second indication received from the second authentication server but not based on the first indication received from the first authentication server.

A system comprising:

• at least one network device including a hardware processor configured to perform operations comprising:
• receiving a first client authentication information comprising a first indication that a first client device was successfully authenticated by a first authentication server based on credentials provided by the first client device;
• forwarding the first client authentication information to a second authentication server without determining that the client device were already successfully authenticated by the first authentication server based on the credentials provided by the first client device;
• receiving, from the second authentication server, a second indication that the first client device was successfully authenticated;
• and
• based on the second indication received by the system from the second authentication server:
• granting network access to the first client device.

A computer system comprising:

• a hardware processor;
• and
• a first authentication server being configured to perform operations configured to execute on the hardware processor comprising:
• subsequent to a first client device being authenticated by a second authentication server:
• receiving from a system (a) a request to authenticate the first client device for network access and (b) a first client authentication information comprising a first indication that the first client device has already been authenticated, wherein the system has forwarded the first client authentication information to the first authentication server without determining that the first client device has already been authenticated,
• wherein the system comprises one or more network devices,
• determining that the first client device is authenticated for network access based on the first client authentication information comprising the first indication that the first client device has already been authenticated, and
• transmitting, to the system, a second indication that the first client device is authenticated to access the network,
• wherein the system provides network access to the first client device based on the second indication received from the first authentication server but not based on the first indication received from the second authentication server.
