Privilege Manager for Unix 6.1 Common Documents - Administration Guide

Configuring Network Address Translation (NAT)

To configure Privilege Manager to allow the use of Network Address Translation (NAT), you must add both the external and internal IP address of the firewall to tunnelrunhosts list in the /etc/opt/quest/qpm4u/pm.settings file.

See PM settings variables for more information about modifying the Privilege Manager configuration settings.

Configuring Kerberos encryption

You can configure Privilege Manager to use Kerberos encryption to authenticate and to exchange encryption key information

To configure Privilege Manager to use Kerberos encryption, edit or insert the following line in the /etc/opt/quest/qpm4u/pm.settings file:

kerberos yes

Also, to use Kerberos with Privilege Manager, ensure that suitable Service Principal Names (SPNs) are registered. Using the generic host service-type, configure the SPNs like this:

host/sun17.quest.com

If the SPN has been registered using the fully qualified DNS name, you can abbreviate the SPNs to the service-type, such as:

host

Specify the service principal names using the mprincipal and lprincipal settings in the pm.settings file. For example, on an agent with a host name of sun17.quest.com, and a SPN registered as db_serve1.quest.com, specify:

mprincipal host 
lprincipal host/db_server1.quest.com

You may need to modify these other settings according to your Kerberos configuration:

See PM settings variables for more information about modifying the Privilege Manager configuration settings.

Configuring certificates

You can enable configurable certification for use with Privilege Manager. Configurable certification is a method of proprietary certification based on the system hardware ID, MD5 checksums and DES encryption.

Use the pmkey command to generate and install certificates. For example, to generate a new certificate and put it into the specified file, enter:

# pmkey -a <filename>

To install the newly generated certificate from the specified file, enter:

# pmkey -i <filename>

Enable configurable certification

To enable configurable certification

1. Ensure that you have configured a Privilege Manager policy server and a Privilege Manager client.
2. Add the following statement to the /etc/opt/quest/qpm4u/pm.settings file on each host:

   certificates YES

3. To generate a key on the Privilege Manager policy server, enter:

   # pmkey –a <policy server filename>

   When prompted, enter a phrase or keyword.

4. To install the key on the Privilege Manager policy server, run

   # pmkey -i <policy server filename>

   NOTE: You must enter the same filename in both the -a and -i commands shown above.

5. To generate a key on each Privilege Manager client, enter:

   # pmkey –a <client filename>

   When prompted, enter a phrase or keyword. Note: you must use the same phrase or keyword to generate the client and policy server certificates.

6. To install the key on the Privilege Manager client, run

   # pmkey -i <client filename>

   NOTE: You must enter the same filename in both the -a and -i commands shown above.

7. Copy the key file you have created on each of the Privilege Manager clients to the Privilege Manager policy server.
8. Copy the key file you have created on the Privilege Manager policy server to the Privilege Manager client.

   The keys are located in /etc/opt/quest/qpm4u/.qpm4u/.keyfiles/<key filename>.

9. On the Privilege Manager policy server, enter:

   # pmkey -i <client filename>

10. On the Privilege Manager client, enter:

    # pmkey -i <policy server filename>

    Configurable certification is now enabled.

    NOTE: By default, pmkey certifies the pass phrase when installing the keyfile for other hosts. If you do not want pmkey to certify the pass phrase when installing the keyfile for other hosts, use -f in the pmkey -i command, like this: # pmkey -i <keyfile> -f
