In the second phase, each login module commits the outcome of its login, updating the JAAS Subject of the current access control context with credentials acquired during the login phase.
在第二个阶段，每个登录模块提交它的登录的结果，用在登录阶段获取的凭证更新当前访问控制上下文的JAAS Subject。
For example, for a queue, an MQQUEUE profile is used to control MQI access to the queue, but other profiles in the MQADMIN class are used to control context and alternate user security.
例如，对于队列，使用一个MQQUEUE概要文件来控制对该队列的访问，但是mqadmin类中的其他概要文件用于控制上下文和用户安全性。
Additionally, the MQADMIN class profiles contain the string QUEUE for profiles used for command resource security, or CONTEXT, for the profiles used to control access to message CONTEXT.
此外，mqadmin类概要文件包含针对用于资源安全性命令的概要文件的字符串QUEUE，或者用于控制对消息CONTEXT的访问的概要文件的字符串CONTEXT。
If CONTROL access is granted to a group, such as AP2USRS, it would allow users in that group to set both origin and identity context.
如果CONTROL访问权授予一个组，比如ap2usrs，那么它将允许该组中的用户设置原始和身份上下文。
Application context can be useful for the purposes of enforcing fine-grained access control and enhances the security of database.
通过实际应用来看，应用上下文技术可以用于提高细粒度访问控制的性能，从而提高数据库的安全性。
In this paper, we present an access control scheme that can resolve these issues, and propose a dynamic context-aware access control model (DCAAC) which extends RBAC with context constraints.
本文提出了一个上下文感知的访问控制模型(DCAAC)，D CAAC扩展了RBAC模型，增加了上下文约束。
