The certificate´s subject CN is different then -H Hostname.
That´s why it is failing with the error message:
Code: Select all
TLS: hostname does not match CN in peer certificate
We already know this is a security thread, anyway by creating the file ~./ldaprc in the nagios user environment files with:
He ignores the differences and gives the right output in the command line, but not on the Nagios portal.
I think that the ~./ldaprc is not loaded with nagios user environment variables. Thus failing on the portal output.
Is there a config file where we define which user environment files are loaded with the portal?
Thanks for the help,
Fred

That's likely it. We can confirm it by running the following commands,
Code: Select all
su - nagios
/usr/local/nagios/libexec/check_nrpe -H <hostaddress> -p 6666 -t 30 -c check_ldap6 --v2-packets-only
The nagios user doesn't have a home directory, so no ldaprc. You can create one for the nagios user, and then add the ldaprc file for it to parse.

Hi,
Topic can be closed, added the .ldaprc file to the application root directory and restarted the services.
File got parsed and the checks are also working on the Nagios Portal now.
There is a difference between the users home directory and the Nagios applications home directory:
Code: Select all
Users Home directory:
/export/home/winnagio
Code: Select all
Applications Root Directory:
/omd/sites/winnagio
Code: Select all
ls -ltra:
winnagio@xxxxxxxxxxxx:/omd/sites/winnagio> ls -ltra
