Splunk Support for Active Directory: "SSLError at "/opt/splunk/lib/python2.7/ssl.py"...sslv3 alert handshake failure"

[cam343]

Hello,

I am attempting to configure SA-ldapsearch on our Splunk 6.3.1 cluster with search head cluster.

I have installed SA-Ldapsearch on the deployer and pushed the bundle, no issue there. I am logging into a particular search head with the intention to configure the domain connections (and eventually copy the config back to the deployer) but attempting to configure the first domain, clicking "Test Connection" it errors with:

Connection test for default failed
 Search
| ldaptestconnection domain="default"
Result
distinguishedName: DC=acme,DC=com
Error
SSLError at "/opt/splunk/lib/python2.7/ssl.py", line 788 : [SSL: SSLV3_ALERT_HANDSHAKE_FAILURE] sslv3 alert handshake failure (_ssl.c:595)"

Testing from our test environment to the same Domain Controller works. So I'm thinking something in our production environment is different. Debugging via

./splunk cmd btool server list --debug

doesn't show anything too different outside of the clustering config etc.

Any suggestions on where to troubleshoot will be appreciated.

Maybe an issue with the rootca, is-it different between the file content in

[sslConfig]
sslRootCAPath=<path>
