LDAP ca-bundle ignored

ldap

#1

I’ve just upgraded to 4.13.3 Community. We are using our own TLS CA for ldap authentication, as usual I’ve updated: .rccontrol-profile/etc/ca-bundle.crt

The rhodecode refuses to authenticate:

admin->settings->system info reports:

RhodeCode Certificate: /home/rhode/.rccontrol-profile/etc/ca-bundle.crt

I checked auth_ldap.py and saw that it was making reference to “/etc/openldap/cacerts”. We are running on Ubuntu 1604 server, I created ran the following as root:
mkdir /etc/openldap
ln -s /etc/ssl/certs /etc/openldap/cacerts

Rhodecode now accepts authentication requests, obviously I have the appropriate CA cert in the ssl/certs directory. I’m not entirely sure why .rccontrol-profile/etc/ca-bundle.crt is now ignored, is this a know issue?

Tnks,

Hi,

Thanks for reporting this. It’s not a known issue. From what version you have upgraded ?

Might be that some things changed in ldap drivers that we haven’t noticed.

Best,


#3

Previous version:

vcsserver/community 4.12.4
rhodecode-control-1.18.0

I noticed python-ldap has had a but of a bump:
python2.7-python-ldap-3.1.0
python2.7-python-ldap-2.4.45


#4

There’s no notice about certificate behaviour change in python-ldap library.
Also based on the code::

https://code.rhodecode.com/rhodecode-enterprise-ce/files/59b28fe5e1537b44b6be2a8c706f64a8f7af0e6f/rhodecode/authentication/plugins/auth_ldap.py#L243-247

This seems to not change between 4.12 and 4.13. This is odd…
