To delete a user, use the ilomconfig delete user command. The –y option prevents the yes or no confirmation prompt. When you specify an XML file name, the command modifies information defined in the exported service processor configuration XML file rather than modifying Oracle ILOM.
# ilomconfig delete user username [-y] [--xmlfile=filename.xml]
where username is the user to delete and filename.xml is the name of the exported service processor configuration XML file to modify.
