to generate a certificate-signing request. You must then send the certificate-signing request to a certificate authority and make arrangements to procure a certificate. When the certificate is received, it is then imported into the IMM through the Import a Signed Certificate link, and you can enable SSL. The function of the certificate authority is to verify the identity of the IMM. A certificate contains digital signatures for the certificate authority and the IMM. If a well-known certificate authority issues the certificate or if the certificate of the certificate authority has already been imported into the Web browser, the browser can validate the certificate and positively identify the IMM Web server. The IMM requires a certificate for the secure Web server and one for the secure LDAP client. Also, the secure LDAP client requires one or more trusted certificates. The trusted certificate is used by the secure LDAP client to positively identify the LDAP server. The trusted certificate is the certificate of the certificate authority that signed the certificate of the LDAP server. If the LDAP server uses self-signed certificates, the trusted certificate can be the certificate of the LDAP server itself. Additional trusted certificates must be imported if more than one LDAP server is used in your configuration. SSL server certificate management The SSL server requires that a valid certificate and corresponding private encryption key be installed before SSL is enabled. Two methods are available for generating the private key and required certificate: using a self-signed certificate and using a certificate that is signed by a certificate authority. If you want to use a self-signed certificate for the SSL server, see "Generating a self-signed certificate." If you want to use a certificate-authority-signed certificate for the SSL server, see "Generating a certificate-signing request." Generating a self-signed certificate To generate a new private encryption key and self-signed certificate, complete the following steps: 1. In the navigation plane, click Security. 2. In the SSL Server Configuration for Web Server area, make sure that the setting is Disabled. If it is not disabled, select Disabled and then click Save. Notes: a. The IMM must be restarted before the selected value (Enabled or Disabled) takes effect. b. Before you can enable SSL, a valid SSL certificate must be in place. c. To use SSL, you must configure a client Web browser to use SSL3 or TLS. Older export-grade browsers with only SSL2 support cannot be used. 3. In the SSL Server Certificate Management area, select Generate a New Key and a Self-signed Certificate. 4. Type the information in the required fields and any optional fields that apply to your configuration. For a description of the fields, see "Required certificate data" on page 41. After you finish typing the information, click Generate Certificate. Your new encryption keys and certificate are generated. This process might take several minutes. You see confirmation if a self-signed certificate is installed.

to generate a certificate-signing request. You must then send the certificate-signing

request to a certificate authority and make arrangements to procure a certificate.

When the certificate is received, it is then imported into the IMM through the

Import a Signed Certificate

link, and you can enable SSL.

The function of the certificate authority is to verify the identity of the IMM. A

certificate contains digital signatures for the certificate authority and the IMM. If a

well-known certificate authority issues the certificate or if the certificate of the

certificate authority has already been imported into the Web browser, the browser

can validate the certificate and positively identify the IMM Web server.

The IMM requires a certificate for the secure Web server and one for the secure

LDAP client. Also, the secure LDAP client requires one or more trusted certificates.

The trusted certificate is used by the secure LDAP client to positively identify the

LDAP server. The trusted certificate is the certificate of the certificate authority that

signed the certificate of the LDAP server. If the LDAP server uses self-signed

certificates, the trusted certificate can be the certificate of the LDAP server itself.

Additional trusted certificates must be imported if more than one LDAP server is

used in your configuration.

SSL server certificate management

The SSL server requires that a valid certificate and corresponding private

encryption key be installed before SSL is enabled. Two methods are available for

generating the private key and required certificate: using a self-signed certificate

and using a certificate that is signed by a certificate authority. If you want to use a

self-signed certificate for the SSL server, see “Generating a self-signed certificate.”

If you want to use a certificate-authority-signed certificate for the SSL server, see

“Generating a certificate-signing request.”

Generating a self-signed certificate

To generate a new private encryption key and self-signed certificate, complete the

following steps:

In the navigation plane, click

Security

In the

SSL Server Configuration for Web Server

area, make sure that the

setting is

Disabled

. If it is not disabled, select

Disabled

and then click

Save

Notes:

The IMM must be restarted before the selected value (

Enabled

Disabled

)

takes effect.

Before you can enable SSL, a valid SSL certificate must be in place.

To use SSL, you must configure a client Web browser to use SSL3 or TLS.

Older export-grade browsers with only SSL2 support cannot be used.

In the

SSL Server Certificate Management

area, select

Generate a New Key

and a Self-signed Certificate

Type the information in the required fields and any optional fields that apply to

your configuration. For a description of the fields, see “Required certificate

data” on page 41. After you finish typing the information, click

Generate

Certificate

. Your new encryption keys and certificate are generated. This

process might take several minutes. You see confirmation if a self-signed

certificate is installed.
