Handle '\n' line breaks in PEM-encoded SSL/TLS certificates
Handle '\n' line breaks in PEM-encoded SSL/TLS certificates

For example Podman, handling OCI containers, does not seem to have
a way to pass multi-line strings via env files (and Docker seems to
have the same issue at least outside of docker-compose). Thus this
change allows 'LDAP_CA_CERT' to handle a string with '\n', because
currently only 0x0A aka LF might work. An example for additionally
supported format:

LDAP_CA_CERT=-----BEGIN CERTIFICATE-----\n...\n...\n...\n-----END CERTIFICATE-----
