IdentityServer - Identity & Access Control mechanism

Identity server is an identification management software component, created for fast growing companies, to fulfil their business requirements. It allows us to gather all information about the identity of employees, partners, and suppliers in one place, helping us to enact suitable policy about permissions to specific information in our business. Identity server is the key to our entire information, services, internal and external relationships. Businesses dealing with multi-module applications, that cover client and service programs, should definitely implement Identity Server. Otherwise, building authentication and authorization mechanisms will be more time and resource consuming, leading to less flexible and unstable system, unsuitable for further development. Thanks to Identity Server, software maintenance becomes one organism, where configuration for clients and service applications becomes isolated.
