A method in a communications system comprising: storing, at the communications system, information associating each of a plurality of users with a uniform resource identifier, and using information derived from credentials associated with each of a plurality of users, wherein credential comprises a first information to determine a resource identifier associated with a connection request for identifying a user and a second information for authenticating the identified user; receiving, using a network interface of the communications system, the credential associated with the connection request; determining a uniform resource identifier associated with the connection request; identifying, based upon the determined uniform resource identifier associated with the connection request and at least a portion of the stored information associating each of a plurality of users with a uniform resource identifier, a first user associated with the determined uniform resource identifier associated with the connection request, the uniform resource identifier being unique to the first user; determining, using a microprocessor of the communications system, whether the received credential associated with the connection request is valid for the first user, wherein determining whether the received credential is valid comprises comparing information derived from the received credential with stored information derived from a credential associated with the first user; characterized in responsive to a determination that the received credential is not valid for the first user associated with the determined uniform resource identifier associated with the connection request: denying access to resources associated with the determined uniform resource identifier; and communicating with the first user, information regarding the determination that the received credential is not valid for the first user. storing, at the communications system, information associating each of a plurality of users with a uniform resource identifier, and using information derived from credentials associated with each of a plurality of users, wherein credential comprises a first information to determine a resource identifier associated with a connection request for identifying a user and a second information for authenticating the identified user; receiving, using a network interface of the communications system, the credential associated with the connection request; determining a uniform resource identifier associated with the connection request; identifying, based upon the determined uniform resource identifier associated with the connection request and at least a portion of the stored information associating each of a plurality of users with a uniform resource identifier, a first user associated with the determined uniform resource identifier associated with the connection request, the uniform resource identifier being unique to the first user; determining, using a microprocessor of the communications system, whether the received credential associated with the connection request is valid for the first user, wherein determining whether the received credential is valid comprises comparing information derived from the received credential with stored information derived from a credential associated with the first user; characterized in responsive to a determination that the received credential is not valid for the first user associated with the determined uniform resource identifier associated with the connection request: denying access to resources associated with the determined uniform resource identifier; and communicating with the first user, information regarding the determination that the received credential is not valid for the first user. denying access to resources associated with the determined uniform resource identifier; and communicating with the first user, information regarding the determination that the received credential is not valid for the first user.
