Red Hat Bugzilla – Bug 981058
openssh-ldap ignores some configuration variables
Last modified: 2015-07-30 02:14:19 EDT
Description of problem:
Utility ssh-ldap-helper ignores some of options from its configuration file (/etc/ssh/ldap.conf). If one need to enable SSL but without checking CA, it should be configured with "tls_checkpeer" set to "allow". But ssh-ldap-helper set it into "hard" in anyway.
Same problem is with option "bind_policy".
Version-Release number of selected component (if applicable):
5.3p1-84.1.el6 (on centos 6)
Steps to Reproduce:
1. Configure LDAP with self-signed certificate (I use Windows AD 2012 as LDAP server).
2. In SSH config file:
- enable SSL
- set tls_checkpeer to something different from "hard", eg. "allow"
3. Run ssh-ldap-helper in debug mode: `/usr/libexec/openssh/ssh-ldap-helper -dvvv -s LDAPUserName
Can't connect to server with self-signed certificate.
From debug mode:
debug3: TLS_CheckPeer Hard
ldap_simple_bind Can't contact LDAP server
Is connected to server with self-signed certificate and returns sshPublicKey.
From debug mode:
debug3: TLS_CheckPeer Allow
Exact config options:
binddn cn=bind user,cn=Users,dc=test,dc=env

Fix LDAP extension
It looks like there are more than one occurrence of this error which makes these problems TLS_CheckPeer and Bind_Policy (as mentioned in original description) in ldap.patch
Here is patch of patch, which should solve this behaviour. But I'm not sure if I will be able to test it.
Also applicable for f20, f21 and rawhide.
This message is a notice that Fedora 19 is now at end of life. Fedora
has stopped maintaining and issuing updates for Fedora 19. It is
Fedora's policy to close all bug reports from releases that are no
longer maintained. Approximately 4 (four) weeks from now this bug will
be closed as EOL if it remains open with a Fedora 'version' of '19'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.
Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 19 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

I'm having this issue on a fully patched Centos6: openssh-ldap-5.3p1-104.el6_6.1.x86_64
This is fixed in last openssh release (openssh-5.3p1-112) even in RHEL. RHEL 6.7 is out, so you will probably have to wait for CentOS folks to rebuild it.
Also having this issue on fully patched Centos7: openssh-ldap-6.6.1p1-12.el7_1.x86_64
Yes, fix for RHEL 7 is also on its way out.
