LDAP check is failing since new certificate

[NMFSTeam]

Good afternoon,

Our centralized LDAP server had its SSL certificate replaced recently. Ever since, our service check in Nagios XI has been failing with the error "Could not bind to the LDAP server."

[root@servername libexec]# ./check_ldap -H ldapserver.address -b "o=valid.o" -2 -S -p 636
Could not bind to the LDAP server

I am thinking we need to update the SSL certificate somewhere, but I don't know where to do it. Please help!

Hello, @mblower. You can add a new certificate in the LDAP menu. Please see the screenshot below.

I have done this, but the error remains. Do I need to restart a service?

@mblower, No problem! I'll be closing this thread as resolved.
