Renewal of security certificates of supplicants

An authenticator device comprising:

• a processor;
• and
• a memory coupled to the processor, the memory storing instructions executable by the processor to:
• receive, from a supplicant device, a request to authenticate the supplicant device based on a security certificate of the supplicant device, wherein the request comprises information relating to the security certificate which is expired;
• determine a login history of the supplicant device and presence of a valid account associated with the supplicant device in a directory database, wherein the valid account has a login credential;
• send an authentication successful message to the supplicant device based on the login history and presence of the valid account in the directory database;
• redirect the supplicant device to a captive web portal for authentication of the supplicant device based on the login credential;
• and
• provide a renewed security certificate for the supplicant device, in response to successful authentication of the supplicant device in the captive web portal.

A non-transitory computer readable medium comprising instructions which, when executed by a processor, causes the processor to:

• receive, from a supplicant device, a request to authenticate the supplicant device based on a security certificate of the supplicant device, wherein the request comprises information relating to the security certificate which is expired;
• determine a login history of the supplicant device and presence of a valid account associated with the supplicant device in a directory database, wherein the valid account has a login credential;
• send an authentication successful message to the supplicant device based on the login history and presence of the valid account in the directory database;
• redirect the supplicant device to a captive web portal for authentication of the supplicant device based on the login credential;
• and
• provide a renewed security certificate for the supplicant device, in response to successful authentication of the supplicant device in the captive web portal.
