SA does not show the full certificate chain by default. You can customize the SSL configuration to enable this feature.

Below is the procedure to enable Security Analytics to serve up the full certificate chain,

1. edit /etc/httpd/conf.d/ssl.conf and uncomment the "SSLCertificateChainFile /etc/pki/tls/certs/server-chain.crt". 

From
#SSLCertificateChainFile /etc/pki/tls/certs/server-chain.crt 

to 

SSLCertificateChainFile /etc/pki/tls/certs/server-chain.crt 

2. Create the server-chain.crt file using a text editor:  vi /etc/pki/tls/certs/server-chain.crt 

3. Add the contents of the subCA.crt and rootCA.crt into the "server-chain.crt" file. 
# 
openssl x509 -text -in /etc/pki/tls/certs/rootCA.crt >> /etc/pki/tls/certs/server-chain.crt 
openssl x509 -text -in /etc/pki/tls/certs/subCA.crt >> /etc/pki/tls/certs/server-chain.crt 

4. Now verify the chain using openssl s_client -connect, 

# openssl s_client -connect 10.10.10.10:443
