I am trying to migrate a Redmine instance from one server to another. The last bit that I am trying to get working is to connect Redmine to OpenLDAP.
My server configuration (details attached) is an Ubuntu 16.04.04 Server, with OpenLDAP 2.4.42 and Redmine 3.4.4. Note that this machine has a self-signed security certificate.
I am able to connect to the LDAP server with Apache Directory Studio and also ldapsearch on the command line.
LDAPTLS_REQCERT=never ldapsearch -D "cn=admin,dc=ubuntutest" -W -p 389 -h ubuntutest -b "dc=ubuntutest" -s sub -x -ZZ "(objectclass=*)"
When I configure the LDAP connection in Redmine and test it, I get the following error.
Unable to connect (SSL_connect SYSCALL returned=5 errno=0 state=SSLv2/v3 read server hello A)
I have a feeling this has to do with the self signed cert in some way, but I am not sure where to start looking here.

LDAPS will use a different port than LDAP. The default ports are 389 for LDAP and 636 for LDAPS.
There is a different LDAP mode called START_TLS which is currently not supported by Redmine. LDAP+START_TLS will be using the same port as plain LDAP, i.e. 389 by default. Maybe ldap_search is using this mode of operation?
