Engine AAA LDAP startTLS Protocol Issue
Hi, Trying to configure Engine to authenticate against OpenLDAP and I seem to be hitting a protocol bug. Attempts to test the login during the setup fail with 2018-02-07 12:27:37,872Z WARNING Exception: The connection reader was unable to successfully complete TLS negotiation: SSLException(message='Received fatal alert: protocol_version', trace='getSSLException(Alerts.java:208) / getSSLException(Alerts.java:154) / recvAlert(SSLSocketImpl.java:2033) / readRecord(SSLSocketImpl.java:1135) / performInitialHandshake(SSLSocketImpl.java:1385) / startHandshake(SSLSocketImpl.java:1413) / startHandshake(SSLSocketImpl.java:1397) / run(LDAPConnectionReader.java:301)', revision=0) Running a packet trace I see that it's trying to negotiate with TLS 1.0, but my LDAP server only support TLS 1.2. This looks like a regression as it works fine in 4.0. I see the issue in both 4.1 and 4.2 4.1.9.1 4.2.0.2 Should I submit a bug? Thanks, Alan

I've sent a fix: https://gerrit.ovirt.org/87327 To workaround it just please add to you profile properties file: pool.default.ssl.startTLSProtocol = TLSv1.2

4.1.9.1 4.2.0.2
