Default Trust Behavior of Agent for Apache HTTP Server on Linux Systems

This section only applies when Access Manager itself is running SSL. By default, the web agent installed on a remote Apache HTTP Server instance will trust any server certificate presented over SSL by the Access Manager host. The web agent does not check the root Certificate Authority (CA) certificate. If the Access Manager host is SSL-enabled and you want the agent to perform certificate checking, adhere to the guidelines as described in the following subsections:

• Disabling the Default Trust Behavior of Agent for Apache HTTP Server on Linux Systems

• Installing the Access Manager Root CA Certificate for a Remote Apache HTTP Server Instance on Linux Systems

Disabling the Default Trust Behavior of Agent for Apache HTTP Server on Linux Systems

The following property in the web agent AMAgent.properties configuration file controls the agent’s trust behavior, and by default it is set to true:

com.sun.am.trust_server_certs

With this property set to true, the web agent does not perform certificate checking. On Linux systems, enabling the web agent to perform certificate checking is a one-step process that only involves setting this property to false as illustrated in the following task.

To Disable the Default Trust Behavior of Agent for Apache HTTP Server on Linux Systems

1. Set the following property in the web agent AMAgent.properties configuration file to false as follows:

   com.sun.am.trust_server_certs = false

Installing the Access Manager Root CA Certificate for a Remote Apache HTTP Server Instance on Linux Systems

The root CA certificate that you install on the remote instance of Apache HTTP Server must be the same one that is installed on the Access Manager host.

To Install the Access Manager Root CA Certificate on Apache HTTP Server on Linux Systems

You can use the certutil program to install the root CA certificate on Apache HTTP Server.

1. Change directories to the location of the Apache HTTP Server configuration file.

   The following example is applicable for changing directories using the C shell when the Apache HTTP Server configuration file is in the default location of /etc/apache/:

   # /etc/apache/

2. Change to the cert directory.

3. Set the proper environment by issuing the following command:

   # setenv LD_LIBRARY_PATH PolicyAgent-base/agents/apache/lib:PolicyAgent-base/agents/lib:/usr/lib/mps

4. (Conditional) If you have not already created the necessary certificate database, create that database now by issuing the following command:

   # PolicyAgent-base/agents/apache/cert/certutil -N -d .

5. Install root CA certificate by issuing the following command:

   # PolicyAgent-base/agents/apache/cert/certutil -A -n cert-name -t "C,C,C" -d cert-dir -i cert-file

   cert-name

   The name for this root CA certificate

   cert-dir

   The directory where the certificate and key stores are located

   cert-file

   The base-64 encoded root CA certificate file.

   For more information on the cetrutil utility enter cetrutil -H for Help.

6. To verify that the certificate is properly installed, in the command line, issue the following command:

   # PolicyAgent-base/agents/apache/cert/certutil -L -d .

   The root CA certificate is then listed in the output of the certutil -L command as illustrated in the following code example:

   Certificate Name Trust Attrubutes cert-name C,C,C p Valid peer P Trusted peer (implies c) c Valid CA T Trusted CA to issue client certs (implies c) C Trusted CA to certs(only server certs for ssl) (implies c) u User cert w Send warning

7. Restart Apache HTTP Server.
