Nagios XI - LDAP / Active Directory - Import Users Certificate Issues
When using the "LDAP / Active Directory Import Users" component in Nagios XI you may receive an error like the following when attempting to login:
Unable to authenticate: TLS error-8179:Peer's Certificate issuer is not recognized.
Issues like these can occur when the certificate you've added to Nagios XI is for a root CA when a subordinate CA is what actually issued the certificate, this subordinate CA certificate will also need to be uploaded.
Resolving the Problem
First step is to remove the existing certificates.
Ensure Environment Is Correctly Setup
Log into your Nagios XI server in an SSH session and execute the following commands:
mkdir -p /etc/openldap/cacerts
The last step is to restart the Apache service using one of the commands below:
RHEL 6 | CentOS 6 | Oracle Linux 6
service httpd restart
RHEL 7 | CentOS 7 | Oracle Linux 7
systemctl restart httpd.service
service apache2 restart
Debian | Ubuntu 16/18
systemctl restart apache2.service
Now add all the required CA certificates.
Once you have completed the above steps the Import Users functionality will work if the CA certificates match the LDAP / Active Directory they are authenticating against.
