Patent ID: 7668831

Claim:
A computer-implemented method of creating an identification profile in a computing environment having multiple user registries, wherein the method comprises: receiving, by an operating system of a clustered computing environment, a command to create a new identification profile; checking by the operating system a plurality of different user registries configured for the operating system to determine whether a candidate identification number for the new identification profile has already been assigned to one or more existing identification profiles, wherein the candidate user identification number is received with the command to create the new identification profile or is provided by the operating system, and wherein the operating system automatically executes the checking in response to the receiving, the plurality of different user registries storing information about the existing identification profiles and comprising at least one logical user registry of the operating system and at least one global user registry of the clustered computing environment, each existing identification profile having associated therewith a unique identification number; and subsequently assigning the candidate identification number to the new identification profile created in a target user registry of the plurality of different user registries if the checking indicates that the candidate identification number has not been assigned already to any of the existing identification profiles, wherein the operating system automatically executes the assigning in accordance with a determination indicated by the checking, the target user registry being one user registry of the plurality of different user registries.
