Jim NormanCommon Authentication Service Adapter (CASA) 1.0 Overview 2.0 Documentation 3.0 Known Issues 4.0 Legal Notices 1.0 Overview Common Authentication Service Adapter (CASA) provides a common infrastructure for client authentication across the Linux* and Microsoft* Windows* desktops. Novell products (such as GroupWise, GroupWise Messenger, iPrint, Novell iFolder, and the Novell clients for Windows and Linux) are integrated with the miCASA interface and can take advantage of the credential store that provides the cornerstone for CASA. The main components of CASA on Linux are: - CASA Identity Development Kit (IDK): The IDK provides a set of APIs that application and service developers can use to write user/application credentials to the credential store. The IDK APIs internally store the credentials passed onto them by the applications in miCASAd. There are C, C++, C# and Java bindings available for the CASA IDK. - miCASAd: An active component that starts during boot time. On Linux, miCASAd is available in the run-levels 1, 2, 3 and 5. It runs with root privileges and is active as long as the system is up. It stores and provides credentials or secrets based on the Linux user identifier (uid) of the process that makes the IDK API calls. The credentials, which are stored by applications in miCASAd, are maintained in memory and written to disk for this release. Session-based secrets implies secrets that are stored in an in-memory cache, are available only as long as the user is in session on the desktop, and are destroyed when miCASA daemon is restarted or the user logs off. When the user logs back in, the secrets written to disk are read back into memory. - Login Credential Capture Module: On Linux, the login credential capture module is implemented as a PAM module. This PAM module captures the user's desktop login credentials and stores them in miCASAd using the IDK APIs. This PAM module is placed as the last module in the auth and session stacks of xdm, gdm, kdm, login and sshd PAM configuration files. The functionality of this module is to store the credentials in miCASAd. Any PAM module that uses the IDK APIs must set its effective user id temporarily to that of the user logging in (the user returned by calling pam_get_user()), if the credentials need to be stored against that user. There might be cases where the user obtained through pam_get_user() might not be the one against whom the PAM module actually intends to store credentials. 2.0 Documentation To read or print the documentation, you need Adobe Acrobat Reader 4.0 (http://www.adobe.com/prodindex/acrobat/readstep.html) . The document in this download was created as a standalone file; therefore, links to files in other downloads will not resolve. The download includes a single file: CASA_Reference_Guide.pdf in the [install directory]\doc directory. 3.0 Known issues - Secrets with IDs using reserved characters may fail. These will be fixed in a future release. Reserved characters are : \ - CASA Manager might report an error stating that miCASA Services are not available when selecting the 'File' option on the main menu. This problem is resolved by upgrading mono to the latest version (1.1.9 or later) available for download at http://www.mono-project.com/Downloads. - CASA install rpm that is intended for 32 bit architecture should not be installed on 64 bit architecture because it can cause runtime problems. 4.0 Legal Notices Novell, Inc. makes no representations or warranties with respect to the contents or use of this documentation, and specifically disclaims any express or implied warranties of merchantability or fitness for any particular purpose.
