certdepot | Create your self-signed SSL certificate | TLS library

In my specific case, I was having this error and I literally spent days scouring the Web for an answer. It turned out in my case that the order matters. It was

1. olcTLSCACertificateFile
2. olcTLSCertificateKeyFile
3. olcTLSCertificateFile

Until the order of the attributes in my file was the one above, I was having that dreaded and unhelpful "ldap_modify: Other (e.g., implementation specific) error (80)" error.

I tried to detect permission errors using sudo -u ldap nano . All was fine for each file.

nano revealed that the files were in DOS format: I converted them to have Linux line endings, to no avail.

In all I read, there was a question as to whether the certificate file was in the proper PEM format. I could not check that, maybe that it's also a cause for this error.

The only thing that worked was commenting out some lines in the file until I saw changes after running ldapsearch -H ldapi:// -Y EXTERNAL -b "cn=config" -LLL -Q -s base.

Note also that I "compressed" the changes in my file to a single change. What I mean with "compressed" is that instead of having three changes, I had only one: instead of this (I'm using Ansible, so this is actually a Jinja2 template)
