Feat ldap ssl

[r4nc0r]

Hi,

I added two enviroment variables for the issue #135:

• HUMHUB_LDAP_CACERT : Here you can insert your certificate and it will be written into the file /etc/ssl/certs/cacert.crt and then added to /etc/openldap/ldap.conf as TLS_CACERT
  example in docker compose:

HUMHUB_LDAP_CACERT: |-
-----BEGIN CERTIFICATE-----
ahfoahofahofhlahfo...
-----END CERTIFICATE-----

• HUMHUB_LDAP_SKIP_VERIFY: if this is set to anything but 0 (zero is the standard value) it will write TLS_REQCERT ALLOW to /etc/openldap/ldap.conf

I tested it locally and it works :)

Perfect! Thank you very much. I will do a short review, I think we can add this soon.
EDIT: It is a very minimalistic change, I like it the way it is 👍 thx again
