Importing Certificates In Imanager

Overview[1]#

When iManager 2.7 is installed on a Linux server (non-OES) Tomcat web service is used for HTTP\HTTPs . The Imanager service uses two sets of certificates for securing two different types of SSL/TLS traffic.

LDAP Certificate#

The LDAP Certificate secures the Imanager and EDirectory.

By default, when a user logs in, Imanager will create a secure LDAP connection to eDirectory. First it will try the the JVM keystore.

If that fails it tries the Imanager specific keystore located in /var/opt/novell/iManager/nps/WEB-INF/iMKS.

Using the default settings, iManager populates this keystore on-the-fly by importing the eDirectory Root Certificate Authority certificate. (This behavior can be changed via the /var/opt/novell/iManager/nps/WEB-INF/config.xml file.)

For more information please see the following:

Tomcat Certificate.#

The Tomcat Certificate and keystore are used for secure HTTPS traffic between a client web browser and iManager's Tomcat service.

The Tomcat Certificate must be accepted by all client browsers connecting to Imanager.

By default, a temporary non-CA signed certificate is generated during the installation of Imanager. The temporary non-CA signed certificate is not signed and has a CN of Temporary Certificate and an expiration date of one year.

We recommend you replace this certificate as soon as possible prior to its expiration.

Moreover, when configuring iChain to authenticate to iManager a certificate chained to a CA must be used or the iChain to iManager authentication will fail.

There are multiple options for replacing the default temporary certificate initially used in iManager\Tomcat. Among the more popular are:

Some Imanager plug-ins require secure LDAP access to function properly.

Refer to Novell documents for the current process

NOTE: This should work for 2.5 and 2.6 also.

NOTE: Imanager Mobile uses the default JDK on the system.

You may want to do this and add the Certificate Authority (CA) to the Keystore then this instance of iManager will work for all servers signed by the CA.

iManager 2.6 docs

This is needed to use some tasks in these roles; here are the known roles that have tasks that require secure LDAP:

On Solaris/Linux, iManager uses the keystore that is part of the JRE it installs on the server.

On Solaris, type: 

cd /opt/novell/jre/bin

On Linux, type: 

cd /opt/novell/java/jre/bin

Then execute this command to import the certificate into the web server's keystore: 

./keytool -import -alias [alias_name] -file [full_path]/trustedrootcert.der -keystore [full_path]/jre/lib/security/cacerts

Here is an example of how to import several certificates into the same iManager instance: 

for cert in `ls -1 ~/certs/*.der`; do
./keytool -import -alias [alias_name] -file [full_path]/trustedrootcert.der -keystore [full_path]/jre/lib/security/cacerts
done

Here is the example output from one such import: 

# ./keytool -import -alias outlaw -file ~/certs/OUTLAW.der -keystore ../lib/security/cacerts 
Enter keystore password:  changeit
Owner: O=OUTLAW, OU=Organizational CA
Issuer: O=OUTLAW, OU=Organizational CA

Certificate fingerprints:

Once the certificates are imported, you should restart Tomcat. Note that the commands listed must be run as 'root' or via sudo.

Solaris:#

/var/opt/novell/tomcat4/bin/shutdown.sh
/var/opt/novell/tomcat4/bin/startup.sh

Linux:#

/etc/init.d/novell-tomcat4 stop
