     Under Debian Stretch, the DHE ciphers are not usable due to a bug

     for details.

  TLS ciphers to enable on the LDAP server. This should be a GnuTLS-compatible

  cipher specification that should also include what TLS protocol versions

  should be used. Value should be compatible with OpenLDAP server option

  ``olcTLSCipherSuite``. Default value allows only TLSv1.2 and strong PFS

  ciphers.

Distribution compatibility

~~~~~~~~~~~~~~~~~~~~~~~~~~

Role is compatible with the following distributions:

- Debian 9 (Stretch)
