LDAP tomcat JNDIRealm

Question

I am using the below server.xml file to configure tomcat to use JNDIRealm to connect to ldap server.

However I keep getting error :

Caused by: javax.naming.CommunicationException: localhost:389 [Root exception is java.net.ConnectException: Connection refused: connect]

I am nowhere using localhost:389 if you see my connection url used host and 636 port. So what is it causing to connect to localhost:389.

Below is server.xml:

Answer 1

Did you try specifying ldaps in the connectionURL setting, ie connectionURL="ldaps://mycompany.org:636"

port 389 is for a non-secure connection
