Hi @mbellerue,

I've followed the steps given in doc. But it's still not able to verify the certificate.

Still getting same error.

Code: Select all

ldap_bind: Can't contact LDAP server (-1)
        additional info: TLS error -8172:Peer's certificate issuer has been marked as not trusted by the user.
Could not bind to the LDAP server
I followed steps given on page number 8 in below document
https://assets.nagios.com/downloads/nag ... ponent.pdf

Also what is the location where i can find the certificate file after uploading it in Nagios?

I'm using
CentOS release 6.8 (Final)
Nagios 5.6.1

Thanks
Vipin

Can you verify that the certificate you're adding is a CA certificate, and not just a server certificate?

Also, are there any proxy servers between the Nagios server and the LDAP server, or CA server (if it's a separate server)?

When uploading the certificate to Nagios XI, it gets placed in /etc/openldap/certs/

Hi @ mbellerue,

Actually it was eDirectory issue, which requires certificate installation.

For now i've followed below link & issue got resolved.
https://sites.google.com/a/geekmungus.c ... ldapserver

but i want to install certificate on client demand.
So below is my ldap.conf file:

Code: Select all

[root@OSLMSnagios openldap]# cat ldap.conf
#
# LDAP Defaults
#

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

#BASE   dc=example,dc=com
#URI    ldap://ldap.example.com ldap://ldap-master.example.com:666

#SIZELIMIT      12
#TIMELIMIT      15
#DEREF          never

#TLS_CACERTDIR  /etc/openldap/certs
TLS_CACERTDIR /cacerts
TLS_CACERT /etc/openldap/certs/ldapsCert.cer
TLS_REQCERT allow
in ldap.conf file, TLS_CACERT /etc/openldap/certs/ldapsCert.cer where ldapCert.cer is the certificate file being used for another server.
So how i can add file location of second certificate to ldap.conf?

Thanks

I am a little confused on what you are trying to do here. Are you trying to add multiple LDAP servers, each of which has its own TLS certificate?
