HP-UX Integrated Login

Notes, Cautions, and Warnings

Notes, Cautions, and Warnings

HP-UX Integrated Login on 10.x is not an upgraded version of DCE-Integrated Login Utilities for 9.x systems. Its activation tool is /usr/sbin/auth.adm. You cannot use dce.login, the 9.x activation tool for DCE-Integrated Login, to activate HP-UX Integrated Login.

When changing passwords using passwd, the password format rules imposed by the login technology restrict the format of newly-entered passwords. A new password that is acceptable to the login technology might be rejected by an additional technology which has more stringent password format rules. To ensure that passwords in all registries can be synchronously changed, configure the login technology to have the password format rules used by the strictest technology employed on that machine.

To change passwords in just one registry, run /usr/bin/passwd with the -roption. The syntax is as follows:

/usr/bin/passwd -r tech_name [username]

where tech_name is one of the approved abbreviations of authentication technologies. For example, the following command changes the DCE password of the logged-in user:

/usr/bin/passwd -r dce

Beginning with DCE 1.3.1, HP-UX Integrated Login provides support for HP-UX Commercial Security. However, note the following restriction and caution. To activate Integrated Login on a Commercial Security Trusted System, you must specify ux as the login technology. Other login technologies can be configured to perform additional authentications after machine access has been granted by the Commercial Security authentication mechanism. If you have configured Integrated Login on a standard system with a login technology other than ux, do not convert that system to a Commercial Security Trusted System. The following example command activates Integrated Login on a Commercial Security Trusted System with DCE as an additional authentication technology:

/usr/sbin/auth.adm -i -l ux -a dce

UX DCE Software specifications

HP UX DCE Software, or Hewlett-Packard UNIX Distributed Computing Environment, represents a significant tool in the realm of distributed system architecture. Designed primarily for enterprise environments, HP UX DCE enhances the reliability, scalability, and manageability of applications over diverse networked systems.

One of the main features of HP UX DCE is its ability to integrate various computing platforms, enabling seamless communication and resource sharing across distributed nodes. This facilitates the creation of complex applications that can operate on a multitude of systems, thus enhancing operational flexibility. DCE employs standardized interfaces, which means applications written for one platform can run on any other platform that supports DCE, promoting cross-platform compatibility.

In terms of technologies, HP UX DCE utilizes Remote Procedure Calls (RPC) as a core feature. This mechanism allows different applications to communicate and invoke procedures on remote systems as if they were local calls. Additionally, DCE includes a robust security model that incorporates Kerberos for authentication, ensuring that communication between nodes remains secure and protected against unauthorized access.

Another significant characteristic of HP UX DCE is its distributed file system, which allows for transparent file access across different machines. The DCE File System (DFS) provides a unified namespace and manages data replication and consistency across distributed storage resources. This reduces the complexity of data management and enhances data availability.

HP UX DCE also supports a variety of programming languages, making it accessible for developers accustomed to different coding environments. This versatility encourages widespread adoption and innovation, as developers can leverage existing skills to create distributed applications.

Furthermore, HP UX DCE is built for high availability, ensuring that critical applications remain responsive even in the face of hardware or network failures. Its inherent component redundancy and fault-tolerant architecture are designed to minimize downtime, which is essential for mission-critical applications in enterprise scenarios.

In conclusion, HP UX DCE Software provides a comprehensive framework for developing, deploying, and managing distributed applications. Its core features such as RPC support, a secure authentication mechanism, a robust file system, and cross-platform compatibility make it a vital resource for organizations aiming to leverage distributed computing effectively. As enterprises evolve, HP UX DCE stands out as an influential solution in the dynamic landscape of distributed environments.
