About HP DCE/9000 Version 1.7

HP Password Management Server

HP Password Management Server

A Password Management Server implements policies for password strength. Sites can implement site-specific policies by writing their own Password Management Server, and attaching appropriate Extended Registry Attributes (ERAs) to the principals that are subject to these policies.

A Password Management Server must implement the interface described in dce/rsec_pwd_mgmt.idl.

In order to be configurable by dce_config or DCM, the Password Management Server must conform to the following guidelines:

•There must be only one Password Management Server per cell.

•The Password Management Server must execute on the same machine as the master DCE Security Server.

•The binary must be named pwd_strengthd.

•The binary must be located in /opt/dce/sbin.

•There must be a single option, -v, on the command line.

•The server must log any information it generates to /var/opt/dce/security/pwd_strengthd.log.

•The server must export its interfaces to CDS in /.:/subsys/dce/pwd_mgmt/pwd_strength.

•The server must use keytab file in /krb5/pwd_strength_tab.

•The server must use principal name and CDS entry name of pwd_strength.

•The server must not depend on any other environment variables or files that must be configured.

Example Sources

Password Management Server sources are supplied in /opt/dce/share/hpexam. These are the sources used to build the Password Management Server supplied with the HP DCE release.

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.
