HP-UX Integrated Login

Activating HP-UX Integrated Login

-ptech_name:param=value[:param=value] specifies the values of parameters applicable to an authentication technology being configured. Parameters of different technologies can be specified by repeating the -p[arameter] option. The list of configurable parameters is as follows:

TIMEOUT — Timeout (in seconds) on communications with authentication technology. Default values are:

u—120 seconds dce—120 seconds

WARNPWDEXP — Password expiration warning period (in days). If the user’s password is due to expire within the specified number of days, the user receives a warning message during login. This parameter applies to DCE technology only. If this parameter is not specified, no warning is given.

FORCEPWDCHANGE — Password force-change period (in days). If the user’s password is due to expire within the specified number of days, the user is forced to change the password before login is allowed. This parameter applies to the DCE technology only. If this parameter is not specified, a password change is not forced.

FORWARDABLETGT — Enable DCE TGT to be forwardable. When forwarding a user’s DCE TGT from machine A to machine B, it enables the user from machine A to reuse its Kerberos credentials on machine B. A parameter value is required, but its content is ignored. This parameter applies to DCE technology only.

Default values are used when no parameter values are specified.

The following example commands activate HP-UX Integrated Login and set the configuration as described:

/usr/sbin/auth.adm -install -l dce -b ux

Configuration is set to log in the user upon successful password verification by DCE. If DCE is not available, login is effected via /etc/passwd. Note that this strategy works only if the HP-UX and DCE passwords are identical:

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

Configuration is set to log in the user upon successful password verification by /etc/passwd. This configuration specifies that after machine access has been granted, a DCE login should also be performed.

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.
