St2-auth-backend-ldap, I think it is not connecting to the server remote_addr=''

(Peter Michael Gits) #1

Don’t know if you are able to assist me, I am using the open source version for ldap, following these directions [GitHub - StackStorm/st2-auth-backend-ldap: Authentication backend for StackStorm which reads authentication information from a LDAP server.] and I suspect that the remove_addr='' is making it fail. I am using the docker version of stackstorm (st2 2.10.1, on Python 2.7.6). Below are the logs st2auth.log, I have also attached the st2.config section of auth below and the ldap.con. Any guidance would certainly help. I have been able to do a ldapsearch successfully from the command line in linux given the tools I installed from the link above.

    # Base URL to the API endpoint excluding the version (e.g.
    api_url =


# LDAP Defaults

# See ldap.conf(5) for details
# This file should be world readable but not world writable.

BASE	dc=fnetworks,dc=com
URI	ldap://
#DEREF		never

# TLS certificates (needed for GnuTLS)
TLS_CACERT	/etc/ssl/certs/ca-certificates.crt

my next step is to debug the python code from the open source, I just don’t think it is picking up the ldap_url properly. Any thoughts or guidance would be welcome.

Maybe another community members be able to help you. We do not provide technical support for the open source version of the LDAP backend.

There is a LDAP backend that comes with the enterprise version of StackStorm. Since we developed and continuously test that version, it is easier for us to provide support for that.

understood. Thanks.
