DCE and DFS for Linux Installation and Configuration Guide

D — GNU GPL Extras


[Previous] [Next] [Contents] [Index]


This appendix describes extra components that can increase the functionality of your DCE/DFS environment, and contains the following sections:

D.1 PAM
D.2 Name Service Switch

All extra components described here are offered under the GNU Public License. Extras include the modules and the source code for them. Entegrity did not develop these modules but may have modified them to work correctly with the Entegrity DCE/DFS product. To view the GNU General Public License (GNU GPL, GPL or LGPL), see http://www.gnu.org/licenses/gpl-howto.html

Use these extra components at your own risk. Entegrity does not promise support for them. However, if you do find a bug, we will try to fix it. If you enhance the components on your own, and you notify us, we can include your enhancements.

As we add and modify extras, we will list them in this appendix, with descriptions and locations.

D.1 PAM

PAM (Pluggable Authentication Module) provides a way to develop programs, independent of authentication scheme. The local system administrator decides which authentication module to attach to a program at runtime, depending on the local system setup. For more information, see

http://www.kernel.org/pub/linux/libs/pam/FAQ

and http://kernel.org/pub/linux/libs/pam/

The Entegrity code is installed in the EXTRAS tree on your CD. In that directory you will find general and configuration information in README, and build instructions in BUILDING. All the source code is located in the src directory. A Makefile is included, for building the code on your target platform.

You can download the PAM code from:

D.2 Name Service Switch

There is a Name Service Switch module available for Entegrity DCE on Linux. With nss_dce, you can specify dce as a source in the nsswitch.conf file and retrieve naming service information directly from the DCE registry. Paul Henson at California State Polytechnic University, Pomona developed the switch. For more detail and to see other DCE projects see http://www.csupomona.edu/~henson/www/projects.
