Hi all
apache-tomcat-8.0.36
java version "1.8.0_281"
Java(TM) SE Runtime Environment (build 1.8.0_281-b09) Java HotSpot(TM)
64-Bit Server VM (build 25.281-b09, mixed mode)
We are having a problem with our Single sign On config.
When using ldap - all works well.
When switiching to ldaps , the User loses to connection all together
(Server not reachable)
server.xml
Good:
<Realm className="org.apache.catalina.realm.JNDIRealm"
connectionURL="ldap://xxxxx.xxxx.com:3268";
userBase="DC=XXXINTRA,DC=CH"
userSubtree="true"
userSearch="(sAMAccountName={0})"
userRoleName="memberOf"
roleBase="OU=PF00_App-
Access,OU=PF00_App,OU=PF00_Server,OU=PF00_Res,OU=PF00,DC=XXXINT
RA,DC=ch "
roleName="CN"
roleSearch="(member:1.2.840.113556.1.4.1941:={0})"
roleSubtree="true"
roleNested="true" />
bad:
<Realm className="org.apache.catalina.realm.JNDIRealm"
connectionURL="ldaps://xxxxx.xxxx.com:3269"
userBase="DC=XXXINTRA,DC=CH"
userSubtree="true"

Connectivity to the DC is fine (ldapsearch with ldaps works), SSL
connection itself seems to be fine, Certificates are fine, we are sending the
trustore as well. All is in the relevant cacerts too.
We have a https Server in Front and a proxy Setting to the tomcat.

org.apache.catalina.startup.Bootstrap start
Domain controller seems to close the connection. The Error is "The
Parameter is incorrect", "The System cannot find the path specified." Its
seems to happen, during the bind process, as if the DC can not decrypt our
tomcat request:
First two events are happening several times. After the last anonymous
bind is entered, the bind exited is done with the appway service account user.
Right after that the error appears.
Internal event: Function ldap_bind entered.

What are we missing?
Because your AD server sees the connection, it's probably not a TLS
handshake failure, but I was wondering if it was a TLS handshake failure.
Recent Java versions have e.g. disabled TLSv1 and TLSv1.1, but I think that
was done at 1.8 patch 291 and you are on patch 281
Maybe you should be using port 3269 instead of 3268? Looks like 3269 is for
TLS and 3268 is for plaintext.
You say that ldapsearch works. Can you post that command-line?
