Description David Spurek 2013-11-07 03:39:55 EST
+++ This bug was initially created as a clone of Bug #1027613 +++

Description of problem:
'tls_reqcert try' option has bad behavior on client side. It should allow connection if certificate is not specified.

man page says:
try    The  server  certificate  is requested. If no cer‐
     tificate is provided, the  session  proceeds  nor‐
     mally.  If a bad certificate is provided, the ses‐
     sion is immediately terminated.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.Setup ldap server with certificates
2.remove all TLS_CACERT and TLS_CACERTDIR from /etc/openldap/ldap.conf
3.set TLS_REQCERT try to /etc/openldap/ldap.conf
4. try ldapsearch -ZZ -x -H ldap://<server_name> '*'

Actual results:
ldapsearch fail:
ldap_start_tls: Connect error (-11)
	additional info: TLS error -8172:Peer's certificate issuer has been marked as not trusted by the user.

Expected results:
ldapsearch should pass

Additional info:

--- Additional comment from David Spurek on 2013-11-07 03:37:52 EST ---

if TLS_REQCERT allow is set then ldapsearch pass. TLS_REQCERT try and allow should have the same behavior in case if no ca cert is specified (according to description in man ldap.conf).
Comment 1 Jan Včelák 2014-08-01 21:53:35 EDT
I think the description talks about the server certificate, not CA certificate.

With the 'try' option, the server will be requested to send it's certificate. The server will send it and the validation will fail on the client side, because you have no CA configured.

The same will happen with 'allow'.

I believe that the 'try' and 'allow' options have no valid purpose at the moment. The server will always send it's certificate. And I guess that these two options are some relict of old SSL versions, where the server didn't have to authenticate to the client.

You should better check with the OpenLDAP upstream.

I forgot add link to upstream discussion - http://www.openldap.org/lists/openldap-technical/201311/msg00099.html
