Confluence LDAPs - javax.net.ssl.SSLHandshakeException | How to Setup TLSv1 for LDAP Access ?
Asked by dennis_schneck:

Hello,

wanna Upgrade to Confluence 7.1.0 from 6.15.x.  
Build a clone to check.  
But the LDAPs connection to MS Active Directory did not work.

Got this error:

nested exception is javax.naming.CommunicationException: adserver.domain:tld \[Root exception is javax.net.ssl.SSLHandshakeException: The server selected protocol version TLS10 is not accepted by client preferences \[TLS12, TLS11\]\]

Using OpenJDK 11  
The Active Directory did only use TLSv1  
How to setup that LDAPs connection work with TLSv1

Tryed: in JDK Dircertoy: conf/security/java.security

jdk.tls.client.protocols="TLSv1,TLSv1.1,TLSv1.2"

But this did not work.

in ../bin/setenv.sh

CATALINA_OPTS="-Djdk.tls.server.protocols=TLSv1,TLSv1.1,TLSv1.2 -Djdk.tls.client.protocols=TLSv1,TLSv1.1,TLSv1.2 ${CATALINA_OPTS}"

Hope this helps

ensure that you have the needed CAs in the file

../jre/lib/security/cacerts

Did you mean only change the ../bin/setenv.sh

CATALINA_OPTS="-Djdk.tls.server.protocols=TLSv1,TLSv1.1,TLSv1.2 -Djdk.tls.client.protocols=TLSv1,TLSv1.1,TLSv1.2 ${CATALINA_OPTS}"

did not work me - login fail

author: Benjamin Heublein
body: I had the same probleme with confluence 7.4.0 connecting to jira 8.5.4 with adoptjdk 11

I reenabled tls V1 by changing the following line in setenv.sh:

CATALINA_OPTS="-Djdk.tls.server.protocols=TLSv1.1,TLSv1.2 -Djdk.tls.client.protocols=TLSv1.1,TLSv1.2 ${CATALINA_OPTS}"

to

CATALINA_OPTS="-Djdk.tls.server.protocols=TLSv1,TLSv1.1,TLSv1.2 -Djdk.tls.client.protocols=TLSv1,TLSv1.1,TLSv1.2 ${CATALINA_OPTS}"

That worked for me but doesn't feel good.

body: Our Problem was that the Apache proxy was still using the unsecure TLSv1.

After reconfiguring our proxy to use just the newer tls versions, the above modification wan't necassary anymore

body: Same here, worked before with 7.0.2, now with 7.2.0 it doesn't.
