  • Patent number: 8839395
    Abstract: A single sign-on (SSO) system uses simple one-to-one trust relationships between individual applications and an SSO service to extend log in services from one application to another. Each application retains its own login policies and can separately make a decision whether to trust the SSO request or challenge the user for login credentials. By structuring the SSO system to use simple identity mapping, there is no requirement for consolidating user identity records from multiple applications into a single database with its attendant overhead and dependency risks.

  • Patent number: 8785685
    Abstract: The present invention relates to a process for preparing aminopolycarboxylates proceeding from an amino acid which, in a first process step is reacted with ethylene oxide to give an intermediate mixture comprising the corresponding dialkanolamine, and then the intermediate mixture, in a second process step is converted catalytically using a base to the corresponding aminopolycarboxylate, wherein the amino acid, before the reaction with ethylene oxide in the first process step, is supplied to a partial neutralization with 0.70 to 0.99 equivalent of base per acid group, or, in the first process step, an amino acid which has already been partly neutralized with 0.70 to 0.99 equivalent of base per acid group is used.
