Nagios Support Forum

Hello, I have a problem with my test environment. The test environment is a server with a Windows Server 2019 license. In this one different VMs are hosted, which are connected to each other in a domain. It is an Active Directory, DHCP, DNS, DFS server. The problem is that Nagios does not report any login errors to the domain controller. In NagiosXI under admin/ LDAP/AD integration it is not possible to import users even though the corresponding VM recognizes the service ldap and domain. Error message = Unable to authenticate: error14 090 086:SSL routine:ssl3_get_server_certificate:certificate verify failed (unable to get local issuer certificate) If I have chosen the wrong approach or if there are several ways to display the Domaincontroller login errors, I would appreciate your feedback.

Have you imported the certificate authority into XI? This would be done in the web UI under Admin > Users > LDAP/AD Integration > Certificate Authority Management.

https://assets.nagios.com/downloads/nag ... d-LDAP.pdf covers this step if you haven't done so already.

If you've already done this, try editing /etc/openldap/ldap.confand and add the line:
and then try to import a user again and let us know your results.
