HP WBEM Services Version A.02.07 Release Notes, September 2009

Table 1-2 Remote User Authentication Methods
HTTP Basic AuthenticationCertificate Based Authentication (CBA)
Description
Using a request/challenge mechanism and authenticating
the user-supplied username and password through
Pluggable Authentication Modules (PAM).
The cimserver requests the client certificate while HTTPS
connection is in progress.
Benefits and Considerations
• Easier to setup, as it does not require any server
configuration.
• Requires the remote user to provide a password each
time to access the WBEM data.
• You will have to update the client application each
time the password is changed.
• Requires a one-time server configuration.
• Does not require the remote user to provide a
password each time to access the WBEM data.
The benefits of not requiring a password include:
• Prevents intruders from gaining access to internal
network resources by “spoofing” passwords.
• Additional configuration or updates to applications is
not required whenever a password is changed.

Authentication” (page 11)
More about using HTTP Basic Authentication
The /etc/pam.conf file is the configuration file for PAM. The /etc/pam.conf file contains
a list of services and each service is mapped to a corresponding service module. When a service
is requested, its associated module is invoked. WBEM Services will default to the authentication
mechanism specified in the OTHER directive of the /etc/pam.conf file. To use other
authentication methods, you must edit the/etc/pam.conf file and add a "wbem" service entry.
See example below. For additional information, please refer to the pam(3) and pam.conf(4)
man pages.
