3. In Windows Explorer, search for the openssl.conf file, and make note of the
directory path for the file. On the DMG4000 Gateway SU4.1, the openssl.conf
file is in the C:\Program Files (x86)\GnuWin32\share\openssl.cnf directory.
4. Execute two openssl req commands to request both a private key file and a
certificate request file. When you execute these commands, you must use the
–config option to point to openssl.conf; otherwise you will get an error.
For example, the following commands request a private key file named
priv.cer and a certificate request file named request.csr. This example uses
the default install location of openssl. You can copy these commands if you
want to use the same install location.
C:\Program Files (x86)\GnuWin32\bin>openssl req -new -nodes -keyout c:\keys\sba
1\priv.cer -out c:\keys\sba1\request.csr -config "C:\Program Files (x86)\GnuWin3
2\share\openssl.cnf"
Output like the following appears:
Loading 'screen' into random state – done
Generating a 1024 bit RSA private key
..............++++++
..........++++++
writing new private key to 'c:\keys\sba1\priv.cer'
-----
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
5. Enter values for the requested fields. The values you enter make up the
Distinguished Name (DN) of the CA certificate. The value for Common Name
is the most important value, and it must be the exact FQDN. Leave the values
for the „extra attributes‟ blank.
For example:
Country Name (2 letter code) [AU]:US
State or Province Name (full name) [Some-State]:NY
Locality Name (eg, city) []:Buffalo
Organization Name (eg, company) [Internet Widgits Pty Ltd]:Dialogic
Organizational Unit Name (eg, section) []:Dialogic Research
Common Name (eg, YOUR name) []:sba1.training.com
Email Address []:
Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:
An optional company name []:
If the openssl requests are successful, the CA places two security files into the
directory you created in Step 2 (c:\Keys\SBA1).
2. Access the Active Directory Certificate Services website from any machine in the
domain where the Microsoft Lync Front End Server is installed. The domain and IP
address will vary, depending on the installation. For example:
http://domain/certsrv
http://172.16.12.21/certsrv
