PFX Method - Creating the Security (TLS) Certificate in the OCS and Exporting the Certificate to the Collaboration Server Workstation
If you are using the PFX method to create and send the security certificate to the
Collaboration Server, certificate files rootCA.pem, pkey.pem and cert.pem must be sent to the
Collaboration Server unit. These files can be created and sent to the Collaboration Server in
two methods:
• The files rootCA.pem, pkey.pem and cert.pem are provided by a Certificate Authority and
are sent independently or together with a password file to the Collaboration Server.
This is the recommended method.
• Alternatively, the TLS certificate files are created internally in the OCS and exported to
the Collaboration Server workstation from where the files can be downloaded to the
Collaboration Server. If the certificate is created internally by the OCS, one *.pfx file is
created. In addition, a text file containing the password that was used during the
creation of the *.pfx file is manually created. Both files can then be sent from the
Collaboration Server workstation to the Collaboration Server unit. When the files are
sent to the Collaboration Server, the *.pfx file is converted into three certificate files:
rootCA.pem, pkey.pem and cert.pem.
Sometimes, the system fails to read the *.pfx file and the conversion process fails.
Resending *.pfx file again and then resetting the system may resolve the problem.
The following procedure describes how to create the *.PFX file in the OCS and export it so it
can be sent to the Certificate Authority or to the Collaboration Server.
To create the TLS certificate in the Office Communications Server:
1In the OCS Enterprise Pools tree, expand the Pools list and the server pool list.
2Right-click the pool Front End entity, and click Certificate.
The Office Communicator Server Wizard Welcome window is displayed.
3Click Next.
The Available Certificate Tasks window appears.
