  • Publication number: 20040088543
    Abstract: A selective cross-realm authenticator associates an identifier with a request from an entity authenticated in one realm to access a resource associated with a second realm. The identifier indicates that the entity was authenticated in a realm other than the realm associated with the requested resource. A domain controller associated with the resource performs an access check to verify that the authenticated user is authorized to authenticate to the requested resource. Permissions associated with the resource can be used to specify levels of access to be granted to entities authenticated by a domain controller associated with another realm.

  • Publication number: 20030212806
    Abstract: Methods and systems are provided to allow users that are authenticated by a trusted external service to gain controlled levels of access to selected local computing resources without requiring the user to also have conventional access control capabilities for the resources.

  • Publication number: 20030119722
    Abstract: Disclosed are methods of purifying glycopeptides that are substituted with one or more substituents each comprising one or more phosphono groups that are useful as antibacterial agents. The methods include contacting a solution of the glycopeptide derivatives with a polystyrene-containing resin, eluting the resin with an aqueous solution, and isolating the purified glycopeptide derivative.

  • Publication number: 20030120948
    Abstract: An enterprise network architecture has a trust link established between two autonomous network systems that enables transitive resource access between network domains of the two network systems. The trust link is defined by data structures maintained by each of the respective network systems. The first network system maintains namespaces that correspond to the second network system and a domain controller in the first network system, or a first network system administrator, indicates whether to trust individual namespaces. An account managed by a domain in the second network system can request authentication via a domain controller in the first network system. The first network system determines from the trust link to communicate the authentication request to the second network system. The first network system also determines from the trust link where to communicate authorization requests when administrators manage group memberships and access control lists.

  • Publication number: 20030018913
    Abstract: Methods and systems are provided for controlling the scope of delegation of authentication credentials within a network environment. A server is configured to provide a trusted third-party with a ticket authenticating the server, information about a target service that a server seeks to access on behalf of the client, and a service ticket associated with the client. This service ticket may be provided by the client or may be a previously granted service ticket granted to the server for itself in the name of the client. The trusted third-party grants a new service ticket to access the target service to the server, in the client's name, if such delegation is permitted according to delegation constraints associated with the client.

  • Patent number: 6355810
    Abstract: Disclosed are multibinding compounds which inhibit 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMG-COA reductase), the rate limiting enzyme in cholesterol biosynthesis. The multibinding compounds of this invention containing from 2 to 10 ligands covalently attached to one or more linkers. Each ligand is a moiety capable of binding to HMG-CoA reductase and the distance between ligands is at least 10 Å. The multibinding compounds of this invention are useful in the treatment and prevention of hypercholesterolemia, hyperlipidemia, atherosclerosis and the like.
