CSR Generation Instructions - Cisco ACS 3.2
To generate a CSR,
you will need to create a key pair for your server. These two items
are a digital certificate key pair and cannot be separated. If you lose
your public/private key file or your password and generate a new one,
your SSL Certificate will no longer match. You will have to request
a new SSL Certificate and may be charged.
VeriSign recommends
that you contact the ACS vendor for additional information.
Step 1: Generate a Key Pair and Certificate
Signing Request
- In the navigation bar, click System Configuration.
- Click ACS Certificate Setup.
- Click Generate Certificate Signing Request. CiscoSecure ACS displays
the Generate new request table on the Generate Certificate Signing Request
page. Fill out all of the requested fields.
- In the Certificate subject box, type the values required by the CA
you will submit the CSR to. Cisco Secure ACS requires that one of the
values be CN, such as CN=acs01primary. You can specify multiple values.
To do so, separate the values with commas. For example:
CN=www.verisign.com, O=VeriSign, C=UK, C=Surrey, L=Guildford.
VeriSign requires, Common Name, Organisation, Town, County and Country.
An Organisation Unit (OU) is optional.
- In the Private key file box, type the full directory path and name
of the file in which the private key is saved, for example, c:\privateKeyFile.pem.
- In the Private key password box, type the private key password that
you would like to use. VeriSign does not have access to this password
and cannot recover it.
- In the Retype private key password box, retype the private key password.
- In the Key length list, choose 1024 bits.
- From the Digest to sign with list, select SHA1.
- Click Submit. CiscoSecure ACS displays a CSR in the display area,
on the right, under a banner that reads: Now your certificate signing
request is ready. You can copy and paste it into any certification authority
enrolment tool. You have just created a key pair and a CSR.
- To copy and paste the information into the enrolment form, open the
file in a text editor that does not add extra characters (Notepad or
Vi are recommended).
- Go to Enrolment. When enrolling for the SSL Certificate you will be
asked to choose a server vendor, choose Apache. This will allow a certificate
that is compatible with the Cisco ACS.
Terms Defined
Common Name
The Common Name
is the Host + Domain Name. It looks like "www.company.co.uk"
or "company.co.uk".
VeriSign certificates
can only be used on Web servers using the Common Name specified during
enrolment. For example, a certificate for the domain "domain.co.uk"
will receive a warning if accessing a site named "www.domain.co.uk"
or "secure.domain.co.uk", because "www.domain.co.uk"
and "secure.domain.co.uk" are different from "domain.co.uk".
Organisation Information
- If your company or department has an &, @, or any other symbol
using the shift key in its name, you must spell out the symbol or omit
it to enrol.
- The “Org Unit” field is the name of the department or organisation
unit making the request.
- The Locality field is the city or town name, for example: Guildford.
- Do not abbreviate the county name, for example: Surrey.
- Use the two-letter code without punctuation for country, for example:
GB.
Contact Information
During the verification
process, VeriSign may need to contact your organisation. Be sure to
provide an email address, phone number, and fax number that will be
checked and responded to quickly. These fields are not part of the certificate.
