I need to specify a CA file to "ssl_client_certificate" directive. This crt is generated by openssl x509 command with "-trustout" parameter, so starts with "----BEGIN TRUSTED CERTIFICATE-----", rather than common "-----BEGIN CERTIFICATE-----".

Nginx will report error:
PEM routines:PEM_read_bio:no start line

Internally, nginx uses openssl's API "SSL_load_client_CA_file()" to load the cert and report this error.

So it's a bug, expected or I mis-configure somewhere?


Thanks.
