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

 

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.

Same here, trying to connect Confluence 7.1.0 to Jira 8.5.1 and getting the TLS error with AdoptOpenJDK 11

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

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.

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

Even though my Windows server isn't 2008 (it's 2012 R2), adding server support for TLS 1.2 in the registry fixed it for me:

https://support.quovadisglobal.com/kb/a433/how-to-enable-tls-1_2-on-windows-server-2008-r2.aspx

I was wrong. It helped, but my problem is not all the way fixed.

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

 

2020-05-14 09:14:48,833 ERROR [https-jsse-nio-8191-exec-21] [crowd.manager.application.ApplicationServiceGeneric] authenticateUser Directory 'LDAP-Server' is not functional during authentication of 'myuser1'. Skipped.

In Admin Panel I got this error if test connection:

Grundlegende Verbindung testen : Fehlgeschlagen srv01.domain.tld:636; nested exception is javax.naming.CommunicationException: srv01.domain.tld:636 [Root exception is javax.net.ssl.SSLHandshakeException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target]

sorry my fail - forgot the cacertfile in the new jdk!

 

It work for me !

  thanks a lot !
