Contact consolidation across multiple services

A method for retrieving contacts from a plurality of federated services, comprising:

• receiving a query from a client application executing on a client device, the query comprising:
• a single sign-on token that identifies a user account of a user, wherein the single sign-on token is a token generated by an identity manager in an instance in which a successful authentication has been achieved, the single sign-on token being provided to the client device for access to the plurality of federated services, and
• a character string;
• determining which ones of the plurality of federated services are to be authenticated using the client application based on an access permission for the client application, the access permission specifying that the user account is permitted to authenticate the ones of the plurality of federated services in an instance of using the client application;
• sending the single sign-on token to an authentication service of the ones of the plurality of federated services that the user has permission to authenticate;
• receiving a plurality of authentication tokens from the authentication service in response to sending the single sign-on token to the authentication service, each of the plurality of authentication tokens identifying the user to a respective one of the plurality of federated services, each of the plurality of authentication tokens having a predefined period of validity for authenticating the user;
• providing a respective authentication token and the character string to a respective connector for each of the plurality of federated services that the user has permission to access;
• receiving a plurality of responses, each of the plurality of responses being received from the respective connector corresponding to each of the plurality of federated services that the user has permission to access;
• and
• providing the plurality of responses to the client application executing on the client device.

A non-transitory, computer readable medium for retrieving contacts from a plurality of federated services, the non-transitory, computer readable medium comprising machine-readable instructions that, when executed by a processor of a computing device, cause the computing device to at least:

• receive a query from a client application executing on a client device, the query comprising:
• a single sign-on token that identifies a user account of a user, wherein the single sign-on token is a token generated by an identity manager in an instance in which a successful authentication has been achieved, the single sign-on token being provided to the client device for access to the plurality of federated services, and
• a character string;
• determine which ones of the plurality of federated services are to be authenticated-using the client application based on an access permission for the client application, the access permission specifying that the user account is permitted to authenticate the ones of the plurality of federated services in an instance of using the client application;
• send the single sign-on token to an authentication service of the ones of the plurality of federated services that the user has permission to authenticate;
• receive a plurality of authentication tokens from the authentication service in response to sending the single sign-on token to the authentication service, each of the plurality of authentication tokens identifying the user to a respective one of the plurality of federated services, each of the plurality of authentication tokens having a predefined period of validity for authenticating the user;
• provide a respective authentication token and the character string to a respective connector for each of the plurality of federated services that the user has permission to access;
• receive a plurality of responses, each of the plurality of responses being received from the respective connector corresponding to each of the plurality of federated services that the user has permission to access;
• and
• provide the plurality of responses to the client application executing on the client device.
