Configuring SSL on a ServerIron ADX
6
Solution: To verify that the certificate chain is properly uploaded on ServerIronADX, connect to
the BP console and enter the show ssl certificate <cert-name> command. Make sure that all of
the intermediate CA certificates are included.
• Symptom: The wrong format was specified when uploading the certificate. For example, the
certificate was obtained in DER format but uploaded in PEM format.
Solution: Check the certificate from the BP console to make sure that it is readable.
• Symptom: The certificate is chained but "enable-certificate-chaining" command is not enabled
under ssl profile
Solution: If chained certificates are used then "enable-certificate-chaining" command is
required under ssl profile definition. The chaining is disabled by default to improve system
performance.
• Symptom: Certificate is signed by Verisign, but it is shown as expired when the client tries to
connect to the ServerIron. This usually occurs if the client browser has an expired copy of the
intermediate CA certificate.
Solution: Refer to the following URL from Verisign Web site. Download the current copy of
intermediate CA certificate and either replace the expired copy on client browser with the new
copy or append the intermediate CA certificate to the server certificate on the ServerIron.

Perform steps 1 and 2 in the following sections to append intermediate CA certificates to
server certificates.
Step 1: Import Server Certificate and Intermediate CA Certificates
To chain SSL certificates, follow these steps:
1. Import the server certificate using the following command:
scp -1 /home/rr/server.crt rr@30.30.1.1:sslcert:chain2cert:pem
2. Import the intermediate CA certificate using the following command:
scp -1 /home/rr/inter.crt rr@30.30.1.1:sslcert:chain2cert:pem
NOTE
In this example, server.crt is issued by intermediate CA. The inter.crt is the intermediate CA
certificate.
NOTE
The order is important. The server certificate should be imported before the intermediate CA
certificate.
NOTE
The same file name should be used (chain2cert in this example) when importing both the server and
intermediate CA certificate.
Step 2: Enable Certificate Chain
By default, for CA signed certificates, the ServerIronADX does not send the entire certificate chain
when presenting the certificate to the client.
