## Abstract

A network entity that allows collaboration among end users of a collaborative application by using different identifiers. The network entity receives an authentication request from a collaborative application to authenticate an end user. The network entity uses a first identifier of the end user that is associated with the network entity to verify that end user is permitted to use the collaborative application and informs the collaborative application that the end user is permitted to use the collaborative application. The network entity receives from the collaborative application a second identifier of the end user that is not associated with the network entity. The second identifier is linked to the first identifier. The network entity allows the second identifier to be used to authenticate the user with the collaborative application without the need to use the first identifier when a collaborative session is begun.
